        Improve timer accuracy for JavaScript Date object on Windows.
        
        Use a combination of ftime and QueryPerformanceCounter.
        ftime returns the information we want, but doesn't have sufficient resolution.
        QueryPerformanceCounter has high resolution, but is only usable to measure time intervals.
        To combine them, we call ftime and QueryPerformanceCounter initially. Later calls will use
        QueryPerformanceCounter by itself, adding the delta to the saved ftime.  We re-sync to
        correct for drift if the low-res and high-res elapsed time between calls differs by more
        than twice the low-resolution timer resolution.
        
        QueryPerformanceCounter may be inaccurate due to a problems with:
        - some PCI bridge chipsets (http://support.microsoft.com/kb/274323)
        - BIOS bugs (http://support.microsoft.com/kb/895980/)

        Partial fix for <rdar://problem/5744037> Gmail out of memory (17455)
        
        I'm removing KJS_MEM_LIMIT for the following reasons:
        
        - We have a few reports of KJS_MEM_LIMIT breaking important web
        applications, like GMail and Google Reader. (For example, if you
        simply open 12 GMail tabs, tab #12 will hit the limit.)

        - Firefox has no discernable JS object count limit, so any limit, even
        a large one, is a potential compatibility problem.
        
        - KJS_MEM_LIMIT does not protect against malicious memory allocation,
        since there are many ways to maliciously allocate memory without
        increasing the JS object count.
        
        - KJS_MEM_LIMIT is already mostly broken, since it only aborts the
        script that breaches the limit, not any subsequent scripts.
        
        - We've never gotten bug reports about websites that would have
        benefited from an unbroken KJS_MEM_LIMIT. The initial check-in of
        KJS_MEM_LIMIT (KJS revision 80061) doesn't mention a website that
        needed it.
        
        - Any website that brings you anywhere close to crashing due to the
        number of live JS objects will almost certainly put up the "slow
        script" dialog at least 20 times beforehand.

        Geoff's theory is that the slowdown was due to copying hash tables when

        should fix the problem.

        (According to Geoff's measurements, in a PLT that exaggerates the

          Incorrect Function.toString behaviour with read/modify/write operators performed on negative numbers

        Test: fast/js/function-toString-parentheses.html

        The problem here was that a NumberNode with a negative number in it had the wrong
        precedence. It's not a primary expression, it's a unary operator with a primary
        expression after it.

        Once the precedence of NumberNode was fixed, the cases from bug 17020 were also
        fixed without trying to treat bracket nodes like dot nodes. That wasn't needed.
        The reason we handle numbers before dot nodes specially is that the dot is a
        legal character in a number. The same is not true of a bracket. Eventually we
        could get smarter, and only add the parentheses when there is actual ambiguity.
        There is none if the string form of the number already has a dot in it, or if
        it's a number with a alphabetic name like infinity or NAN.

        * kjs/nodes.h: Renamed back from ObjectAccess to DotExpr.

        constructs the ExecState. If we changed that, we could remove this export.

        * JavaScriptCore.xcodeproj/project.pbxproj: Re-sorted a few things and
        put the new source files into the kjs group rather than at the top level.

        * kjs/ExecState.cpp:
        (KJS::ExecState::ExecState): Marked inline and updated for data member
        name changes. This is now only for use for the derived classes. Also removed

        (KJS::ExecState::~ExecState): Marked inline and removed all the code.
        The derived class destructors now inclde the appropriate code.
        (KJS::ExecState::lexicalGlobalObject): Removed unneeded special case for

        directly rather than calling functions.
        (KJS::GlobalExecState::GlobalExecState): Added. Calls through to the base
        class constructor.
        (KJS::GlobalExecState::~GlobalExecState): Added.
        (KJS::InterpreterExecState::InterpreterExecState): Added. Moved code to

        Made ExecState inherit from Noncopyable. Reformatted some comments and

        unused savedExec function. Changed seenLabels function to return a reference

        did the same with all data members. Renamed m_thisVal to m_thisValue and
        ls to m_labelStack. Added three new derived classes for each of the
        types of ExecState. The primary goal here was to remove a branch from the
        code in the destructor, but it's also clearer than overloading the arguments
        to the ExecState constructor.

        (KJS::JSGlobalObject::tearOffActivation): Got rid of unneeded static_cast
        (I think I mentioned this during patch review) and used an early exit so that
        the entire contents of the function aren't nested inside an if statement.
        Also removed the check of codeType, instead checking Activation for 0.

        we can do more dynamic resolution based on argument type etc.
        Still picks the first one with the same name, at the moment.
        
        * Make signature comparison code consistent.
        Use the same code for checking meta signatures in
        the method and fallback getters, and avoid a
        QByteArray construction when we can.
        
        * Fix minor memory leak, and handle pointers better.
        Delete the private object in the dtors, and use RefPtrs
        for holding Instances etc.
        
        * Handle method lookup better.
        Allow invocation time method lookup based on the arguments,
        which is closer to QtScript behaviour.  Also, cache the
        method lists and delete them in the QtClass dtor (stops
        a memory leak).
        
        * Improve JS to Qt data type conversions.
        Add some support for Date & RegExp JS objects,
        and provide some metrics on the quality of the
        conversion.
        
        * A couple of fixes for autotest failures.
        Better support for converting lists, read/write only
        QMetaProperty support, modified slot search order...)

        Fix <rdar://problem/5595552> r27608 introduced a 20% increase in JS binary size, 4% increase in WebCore binary size

        - This changes the way JS functions that use Lookup tables are handled.  Instead of using
          one class per function, which allowed specialization of the virtual callAsFunction
          method, we now use one class, PrototypeFunction, which takes a pointer to a static
          function to use as the implementation.  This significantly decreases the binary size
          of JavaScriptCore (about 145k on an Intel only build) while still keeping some of the
          speedup r27608 garnered (SunSpider says this is 1.005x as slow, which should leave some
          wiggle room from the original 1% speedup) and keeps the functions implementations in separate
          functions to help with optimizations.

        Add binding language type to Instance.
        Allows runtime determination of the type of an
        Instance, to allow safe casting.  Doesn't actually
        add any safe casting yet, though.

        Add a helper function to get an Instance from a JSObject*.
        Given an object and the expected binding language, see if
        the JSObject actually wraps an Instance of the given type
        and return it.  Otherwise return 0.

        Move RuntimeObjectImp creations into Instance.
        Make the ctor protected, and Instance a friend class, so
        that all creation of RuntimeObjectImps goes through
        one place.

        Remove copy ctor/assignment operator for QtInstance.
        Instance itself is Noncopyable, so QtInstance doesn't
        need to have these.

        Add caching for QtInstance and associated RuntimeObjectImps.
        Push any dealings with QtLanguage bindings into QtInstance,
        and cache them there, rather than in the Instance layer.  Add
        a QtRuntimeObjectImp to help with caching.

        This bug was caused by var declarations shadowing built-in properties of

        To match Firefox, we've decided that var declarations will never shadow
        built-in properties of the global object or its prototypes. We used to

          <rdar://problem/5675331> REGRESSION(r29266): Reproducible crash in fast/replaced/image-map.html

        The crash resulted from a native object (DumpRenderTree's
        EventSender) causing its wrapper to be invalidated (by clicking a
        link that replaced the document in the window) and consequently
        deallocated. The fix is to use RefPtrs to protect the native object
        from deletion by self-invalidation.

        - fix alignment problem with NaN and Inf globals

        * kjs/fpconst.cpp: Move the contents of this file from here back to
        value.cpp. The reason this was in a separate file is that the DARWIN
        version of this used a declaration of the globals with a different
        type to avoid creating "init routines". That's no longer necessary for
        DARWIN and was never necessary for the non-DARWIN code path.
        To make this patch easy to merge, I didn't actually delete this file
        yet. We'll do that in a separate changeset.

        * kjs/value.cpp: If C99's NAN and INFINITY are present, then use them,

          speed up function calls by making ScopeChain::push cheaper

        This gives a 1.019x speedup on SunSpider.

        After doing this, I realized this probably will be obsolete when the optimization
        to avoid creating an activation object is done. When we do that one we should check
        if rolling this out will speed things up, since this does add overhead at the time
        you copy the scope chain.

        * kjs/object.h: Removed the ScopeChain::release function. It was

        No idea why it was in this header file!

        function that takes another ScopeChain. It was unused. I think we used

        * kjs/scope_chain.h: Changed ScopeChainNode into a struct rather than
        a class, got rid of its constructor so we can have one that's uninitialized,
        and moved the refCount into a derived struct, ScopeChainHeapNode. Made _node
        mutable so it can be changed in the moveToHeap function. Changed the copy
        constructor and assignment operator to call moveToHeap, since the top node
        can't be shared when it's embedded in another ScopeChain object. Updated
        functions as needed to handle the case where the first object isn't on the
        heap or to add casts for cases where it's guaranteed to be. Changed the push
        function to always put the new node into the ScopeChain object; it will get
        put onto the heap when needed later.

        - Optimize variable declarations

        3.5% speedup on SunSpider.

        var statements now result in either assignments or empty statements.
        
        This allows a couple of optimization opportunities:
        - No need to branch at runtime to check if there is an initializer
        - EmptyStatementNodes can be removed entirely (also done in this patch)
        - Assignment expressions get properly optimized for local variables
        
        This patch also includes some code cleanup:
        - Most of the old VarStatement/VarDecl logic is now only used for const declarations, 
          thus it is renamed appropriately
        - AssignExprNode is gone

        AST optimization: Avoid NULL-checking ForNode's child nodes.
        
        0.6% speedup on SunSpider.
        
        This is a proof of concept patch that demonstrates how to optimize
        grammar productions with optional components, like
        
            for (optional; optional; optional) {
                ...
            }
            
        The parser emits NULL for an optional component that is not present.

        Instead of checking for a NULL child at execution time, a node that
        expects an optional component to be present more often than not checks
        for a NULL child at construction time, and substitutes a viable
        alternative node in its place.

        (We'd like the parser to start emitting NULL a lot more once we teach
        it to emit NULL for certain no-op productions like EmptyStatement and
        VariableStatement, so, as a foundation, it's important for nodes with
        NULL optional components to be fast.)

        * kjs/Parser.cpp:
        (KJS::Parser::didFinishParsing): Check for NULL SourceElements. Also,
        moved didFinishParsing into the .cpp file because adding a branch while
        it was in the header file caused a substantial and inexplicable
        performance regression. (Did I mention that GCC is crazy?)

        * kjs/grammar.y:

        * kjs/nodes.cpp:
        (KJS::BlockNode::BlockNode): Check for NULL SourceElements.

        * kjs/nodes.h:
        (KJS::ForNode::): Check for NULL SourceElements. Substitute a TrueNode
        because it's semantically harmless, and it evaluates to boolean in an

        Stop using completions in the execution engine.
        Instead, the completion type and label target are both
        stored in the ExecState.

        * kjs/function.cpp:
        (KJS::FunctionImp::callAsFunction): Removed some unneeded
        exception processing. Updated to call the new execute function
        and to get the completion type from the ExecState. Merged in
        the execute function, which repeated some of the same logic and
        was called only from here.

        Optimized global access to global variables, using a symbol table.
        
        SunSpider reports a 1.5% overall speedup, a 6.2% speedup on 3d-morph,
        and a whopping 33.1% speedup on bitops-bitwise-and.

        * API/JSCallbackObjectFunctions.h: Replaced calls to JSObject:: with
        calls to Base::, since JSObject is not always our base class. This
        was always a bug, but the bug is even more apparent after some of my
        changes.

        (KJS::::staticFunctionGetter): Replaced use of getDirect with call to
        getOwnPropertySlot. Global declarations are no longer stored in the
        property map, so a call to getDirect is insufficient for finding
        override properties.

        * API/testapi.c: 
        * API/testapi.js: Added test for the getDirect change mentioned above.

        * kjs/ExecState.cpp: 
        * kjs/ExecState.h: Dialed back the optimization to store a direct
        pointer to the localStorage buffer. One ExecState can grow the global
        object's localStorage without another ExecState's knowledge, so
        ExecState can't store a direct pointer to the localStorage buffer
        unless/until we invent a way to update all the relevant ExecStates.

        * kjs/JSGlobalObject.cpp: Inserted the symbol table into get and put
        operations.
        (KJS::JSGlobalObject::reset): Reset the symbol table and local storage,

        because it's an EvalNode, not a ProgramNode.

        (KJS::cacheGlobalObject): Replaced put with faster putDirect, since
        that's how the rest of lookup.h works. putDirect is safe here because
        cacheGlobalObject is only used for objects whose names are not valid
        identifiers.

        * kjs/nodes.cpp: The good stuff!

        (KJS::EvalNode::processDeclarations): Replaced hasProperty with
        the new hasOwnProperty, which is slightly faster.

        Instead of finding declarations in a pass following the initial parsing of
        a program, we incorporate the logic directly into the parser.  This lays

        in addition to providing a 0.4% performance improvement in SunSpider.

        UString::Rep*. With globals, the symbol table can outlast the

        its symbol names.

        REGRESSION: 303-304: Embedded YouTube video fails to render- JS errors (16150) (Flash 9)
        
        Get rid of unnecessary and incorrect security checks for plug-ins accessing JavaScript objects. 
        
        The way this used to work was that each NPObject that wrapped a JSObject would have a root object
        corresponding to the frame object (used for managing the lifecycle) and an origin root object (used for
        doing security checks). 
        
        This would prevent a plug-in from accessing a frame's window object if it's security origin was different
        (some parts of the window, such as the location object, can be accessed from frames with different security 
        origins, and those checks are being done in WebCore).
        
        Also, if a plug-in were to access a window object of a frame that later went away, it could lead to that
        Window JSObject being garbage collected and the NPObject pointing to freed memory.
        
        How this works now is that there is no origin root object anymore, and all NPObject wrappers that are created
        for a plug-in will have the root object of the containing frame of that plug-in.

        threads inside the pthread spinlock, which could lead to the GC
        thread blocking on the pthread spinlock itself.

        We now determine and store each thread's stack base when it is
        registered, thus removing the need for any calls to pthread_get_stackaddr_np
        that needed the pthread spinlock.

        Cleaned up the JavaScript grammar a bit.
        
        1. Changed BlockNode to always hold a child vector (which may be empty),
        eliminating a few NULL-check branches in the common execution case.
        
        2. Changed the Block production to correctly report its starting and 
        ending line numbers to the debugger. (It used to report its ending line
        as its starting line.) Also, removed duplicate line-reporting code
        inside the BlockNode constructor.
        
        3. Moved curly braces up from FunctionBody production into parent
        productions. (I had to move the line number reporting code, too, since
        it depends on the location of the curly braces.) This matches the ECMA
        spec more closely, and makes some future changes I plan easier.
        
        4. Fixed statementList* convenience functions to deal appropriately with
        empty Vectors.

        SunSpider reports a small and statistically insignificant speedup.

        - fix http://bugs.webkit.org/show_bug.cgi?id=11231
          RegExp bug when handling newline characters
          and a number of other differences between PCRE behvior
          and JavaScript regular expressions:

          + single-digit sequences like \4 should be treated as octal
            character constants, unless there is a sufficient number
            of brackets for them to be treated as backreferences

          + \8 turns into the character "8", not a binary zero character
            followed by "8" (same for 9)

          + only the first 3 digits should be considered part of an
            octal character constant (the old behavior was to decode
            an arbitrarily long sequence and then mask with 0xFF)

          + if \x is followed by anything other than two valid hex digits,
            then it should simply be treated a the letter "x"; that includes
            not supporting the \x{41} syntax

          + if \u is followed by anything less than four valid hex digits,
            then it should simply be treated a the letter "u"

          + an extra "+" should be a syntax error, rather than being treated
            as the "possessive quantifier"

          + if a "]" character appears immediately after a "[" character that
            starts a character class, then that's an empty character class,
            rather than being the start of a character class that includes a
            "]" character

          + a "$" should not match a terminating newline; we could have gotten
            PCRE to handle this the way we wanted by passing an appropriate option

        Test: fast/js/regexp-no-extensions.html

        * pcre/pcre_compile.cpp:
        (check_escape): Check backreferences against bracount to catch both
        overflows and things that should be treated as octal. Rewrite octal
        loop to not go on indefinitely. Rewrite both hex loops to match and
        remove \x{} support.
        (compile_branch): Restructure loops so that we don't special-case a "]"
        at the beginning of a character class. Remove code that treated "+" as
        the possessive quantifier.
        (jsRegExpCompile): Change the "]" handling here too.

        * pcre/pcre_exec.cpp: (match): Changed CIRC to match the DOLL implementation.
        Changed DOLL to remove handling of "terminating newline", a Perl concept
        which we don't need.

        * tests/mozilla/expected.html: Two tests are fixed now:
        ecma_3/RegExp/regress-100199.js and ecma_3/RegExp/regress-188206.js.
        One test fails now: ecma_3/RegExp/perlstress-002.js -- our success before
        was due to a bug (we treated all 1-character numeric escapes as backreferences).
        The date tests also now both expect success -- whatever was making them fail
        before was probably due to the time being close to a DST shift; maybe we need
        to get rid of those tests.

        Fix <rdar://5578982> ASSERT in HashTable::checkTableConsistencyExceptSize beneath WebNotificationCenter

        The bug was due to a mismatch between HashMap::remove and
        HashTable::checkTableConsistency. HashMap::remove can delete the value
        stored in the HashTable (by derefing it), which is not normally
        allowed by HashTable. It's OK in this case because the value is about
        to be removed from the table, but HashTable wasn't aware of this.

        HashMap::remove now performs the consistency check itself before
        derefing the value.

        Darin noticed that the same bug would occur in HashSet, so I've fixed
        it there as well.

          next round of changes to JSRegExp (formerly PCRE)

        This is a combination of converting to C++, tweaking the API, and adding
        some additional optimizations.

        Future steps will involve getting rid of the use of UTF-8 completely
        (we'll use UTF-16 exclusively instead), eliminating more source files,
        and some more speed-ups.

        SunSpider says the current round is an 0.9% speed-up overall, and a
        5.3% speed-up for regexp.

        * pcre/pcre_exec.cpp: Copied from JavaScriptCore/pcre/pcre_exec.c.
        Added a case that uses computed goto for the opcode loop, but did not turn it on.
        Changed the RMATCH macro to handle returns more efficiently by putting the where
        pointer in the new frame instead of the old one, allowing us to branch to the
        return with a single statement. Switched to new/delete from pcre_malloc/free.
        Changed many RRETURN callers to not set the return value since it's already
        set correctly. Replaced the rrc variable with an is_match variable. Values other
        than "match" and "no match" are now handled differently. This allows us to remove
        the code to check for those cases in various rules.
        (match): All the case statements use a macro BEGIN_OPCODE instead. And all the
        continue statements, or break statements that break out of the outer case use
        a macro NEXT_OPCODE instead. Replaced a few if statements with assertions.
        (jsRegExpExecute): Use new/delete instead of pcre_malloc/free. Removed unused
        start_match field from the match block.

        * pcre/pcre_internal.h: Moved the last few configuration macros from pcre-config.h
        in here. Removed various unused types. Converted from JSRegExpChar to UChar.
        Eliminated pcre_malloc/free. Replaced the opcode enum with a macro that can be
        used in multiple places. Unfortunately we lose the comments for each opcode; we
        should find a place to put those back. Removed ctype_digit.

        * pcre/pcre_maketables.cpp: Copied from JavaScriptCore/pcre/pcre_maketables.c.
        (pcre_maketables): Got rid of the conditional code that allows this to be compiled

          getting characters by indexing into a string is very slow

        This fixes one source of the slowness -- the conversion to an unused
        Identifier as we call the get function from the slot -- but doesn't
        fix others, such as the fact that we have to allocate a new UString::Rep
        for every single character.

        Speeds up string-base64 30%, and at least 0.5% overall.
        But does slow down access-fannkuch quite a bit. Might be worth
        revisiting in the future to see what we can do about that (although
        I did look at a profile for a while).

        * kjs/property_slot.h: Add a new marker for "numeric" property slots;
        slots where we don't need to pass the identifier to the get function.

        (KJS::stringInstanceNumericPropertyGetter): Added. Like indexGetter, but
        takes advantage of setCustomNumeric to avoid creating an Identifier.
        (KJS::StringInstance::getOwnPropertySlot): Changed to use setCustomNumeric.

        Fix regression caused by earlier bitwise and optimisation.  1 & undefined != 1.

        The implementation of JSImmediate::areBothImmediateNumbers relies on 
        (JSImmediate::getTag(immediate1) & JSImmediate::getTag(immediate2)) having 
        a unique result when both immediate values are numbers.

        The regression was due to UndefinedType & NumberType returning NumberType (3 & 1).
        By swapping the value of NumberType and UndefinedType this ceases to be a problem.

        Add a fast path for bitwise-and of two immediate numbers for a 0.7% improvement in SunSpider (4% bitop improvement).

        This only improves bitwise-and performance, as the additional logic required 
        for similar code paths on or, xor, and shifting requires additional operations
        and branches that negate (and in certain cases, regress) any advantage we might
        otherwise receive.

        This improves performance on all bitop tests, the cryptography tests, as well as 
        the string-base64 and string-unpack-code tests.  No significant degradation on

        Convert JavaScript internal function objects to use one class per
        function.  This avoids a switch statement inside what used to be
        the shared function classes and will allow Shark to better analyze
        the code.

        To make this switch, the value property of the HashEntry was changed
        to a union of an intptr_t (which is used to continue handle valueGetters)
        and function pointer which points to a static constructor for the
        individual new function objects.

        Replace the use of floats for immediate values with the use of integers for a 4.5% improvement in SunSpider.

        Unfortunately this change results in NaN, +Inf, -Inf, and -0 being heap allocated now, but
        we should now have faster array access, faster immediate to double conversion, and the 
        potential to further improve bitwise operators in future.

        This also removes the need for unions to avoid strict aliasing problems when extracting

        Put RegExpImp properties into a static hashtable to avoid a slew of

        Factored important bits of regular expression implementation out of

        making RegExp a ref-counted class. (This will help later.)

        There was a mistake in the algorithm used to find an empty slot in the property
        map entries vector; when we were putting in a new property value and not overwriting
        an existing deleted sentinel, we would enlarge the entries vector, but would not
        overwrite the stale data that's in the new part. It was easy to pin this down by
        turning on property map consistency checks -- I never would have landed with this

        matchframe, since I discovered that rrc ("recursive result code") was already the
        exact same thing. Moved the handling of opcodes higher than OP_BRA into the default
        statement of the switch instead of doing them before the switch. This removes a
        branch from each iteration of the opcode interpreter, just as removal of "op"
        removed at least one store from each iteration. Last, but not least, add the
        OP_ASCII_CHAR and OP_ASCII_LETTER_NC functions. Neither can ever match a
        surrogate pair and the letter case can be handled efficiently.

          remove unused PCRE features for speed

        A first step toward removing the PCRE features we don't use.
        This gives a 0.8% speedup on SunSpider, and a 6.5% speedup on
        the SunSpider regular expression test.

        Replaced the public interface with one that doesn't use the
        name PCRE. Removed code we don't need for JavaScript and various
        configurations we don't use. This is in preparation for still
        more changes in the future. We'll probably switch to C++ and
        make some even more significant changes to the regexp engine
        to get some additional speed.

        There's probably additional unused stuff that I haven't
        deleted yet.

        This does mean that our PCRE is now a fork, but I think that's
        not really a big deal.

        * JavaScriptCore.exp: Remove the 5 old entry points and add
        the 3 new entry points for WebCore's direct use of the regular
        expression engine.

        * kjs/config.h: Remove the USE(PCRE16) define. I decided to flip
        its sense and now there's a USE(POSIX_REGEX) instead, which should
        probably not be set by anyone. Maybe later we'll just get rid of it
        altogether.

        * kjs/regexp.h:
        * kjs/regexp.cpp:
        (KJS::RegExp::RegExp): Switch to new jsRegExp function names and
        defines. Cut down on the number of functions used.
        (KJS::RegExp::~RegExp): Ditto.
        (KJS::RegExp::match): Ditto.

        * pcre/dftables.c: (main): Get rid of ctype_letter and ctype_meta,
        which are unused.

        * pcre/pcre-config.h: Get rid of EBCIDIC, PCRE_DATA_SCOPE, const,
        size_t, HAVE_STRERROR, HAVE_MEMMOVE, HAVE_BCOPY, NEWLINE,
        POSIX_MALLOC_THRESHOLD, NO_RECURSE, SUPPORT_UCP, SUPPORT_UTF8,
        and JAVASCRIPT. These are all no longer configurable in our copy
        of the library.

        * pcre/pcre.h: Remove the macro-based kjs prefix hack, the PCRE
        version macros, PCRE_UTF16, the code to set up PCRE_DATA_SCOPE,
        the include of <stdlib.h>, and most of the constants and
        functions defined in this header. Changed the naming scheme to
        use a JSRegExp prefix rather than a pcre prefix. In the future,
        we'll probably change this to be a C++ header.

        * pcre/pcre_compile.c: Removed all unused code branches,
        including many whole functions and various byte codes.
        Kept changes outside of removal to a minimum.

        (jsRegExpCompile): Renamed from pcre_compile2 and changed the
        parameters around a bit.
        (jsRegExpFree): Added.

        * pcre/pcre_exec.c: Removed many unused opcodes and variables.
        Also started tearing down the NO_RECURSE mechanism since it's
        now the default. In some cases there were things in the explicit
        frame that could be turned into plain old local variables and
        other small like optimizations.
        (pchars):
        (match_ref):
        (match): Changed parameters quite a bit since it's now not used
        recursively.
        (jsRegExpExecute): Renamed from pcre_exec.

        * pcre/pcre_internal.h: Get rid of PCRE_DEFINITION, PCRE_SPTR,

        PUBLIC_OPTIONS, PUBLIC_EXEC_OPTIONS, PUBLIC_DFA_EXEC_OPTIONS,
        PUBLIC_STUDY_OPTIONS, MAGIC_NUMBER, 16 of the opcodes,
        _pcre_utt, _pcre_utt_size, _pcre_try_flipped, _pcre_ucp_findprop,
        and _pcre_valid_utf8. Also moved pcre_malloc and pcre_free here.

        * pcre/pcre_maketables.c: Changed to only compile in dftables.
        Also got rid of many of the tables that we don't use.

        * pcre/pcre_tables.c: Removed the unused Unicode property tables.

        for classes based on Unicode properties.

        * wtf/FastMallocPCRE.cpp: Removed unused bits. It would be good
        to eliminate this completely, but we need the regular expression
        code to be C++ first.

        * pcre/pcre_fullinfo.c:
        * pcre/pcre_get.c:
        * pcre/ucp.h:
        Files that are no longer needed. I didn't remove them with this

          change property map data structure for less memory use, better speed

        The property map now has an array of indices and a separate array of
        property map entries. This slightly slows down lookup because of a second
        memory acess, but makes property maps smaller and faster to iterate in
        functions like mark().

        SunSpider says this is 1.2% faster, although it makes the bitwise-end test
        more than 10% slower. To fix that we'll need to optimize global variable lookup.

        AST transfom to replace slow resolve nodes with fast local variable
        alternatives that do direct memory access. Currently, only ResolveNode
        provides a fast local variable alternative. 6 others are soon to come.
        
        16.7% speedup on SunSpider.
        
        Most of this patch is just scaffolding to support iterating all the 
        resolve nodes in the AST through optimizeResolveNodes(). In 
        optimizeResolveNodes(), most classes just push their child nodes onto 
        the processing stack, while ResolveNodes actually replace themselves in 
        the tree with more optimized alternatives, if possible.

        Here are the interesting bits:

        * kjs/nodes.h: Added PlacementNewAdoptTag, along with implementations 
        in Node and ResolveNode. This tag allows you to use placement new to 
        swap out a base class Node in favor of a subclass copy that holds the
        same data. (Without this tag, default initialization would NULL out
        RefPtrs, change line numbers, etc.)

        * kjs/nodes.cpp:
        (KJS::ResolveNode::evaluate): Since we're taking the slow path, ASSERT

          remove GroupNode to simplify AST and possibly get a modest speedup

        This patch removes 4 node types: GroupNode, PropertyNameNode,
        FunctionCallParenBracketNode, and FunctionCallParenDotNode.

        To remove GroupNode, we add knowledge of precedence to the tree nodes,
        and use that when serializing to determine where parentheses are needed.
        This means we no longer have to represent parentheses in the tree.

        The precedence values are named after productions in the grammar from the
        JavaScript standard.

        SunSpider says this is an 0.4% speedup.

        * kjs/function.h:
        * kjs/function.cpp: Removed escapeStringForPrettyPrinting -- it's part of
        serialization, so I moved it to the file that takes care of that.

        * kjs/grammar.y: Changed makeGetterOrSetterPropertyNode to use 0 to
        indicate failure instead of a separate boolean. Got rid of PropertyNameNode
        by merging the PropertyName rule into the Property rule (which was easier
        than figuring out how to pass the Identifier from one node to another).
        Got rid of GroupNode, nodeInsideAllParens(), FunctionCallParenBracketNode,
        and FunctionCallParenDotNode.

        * kjs/nodes.h: Removed unused forward declarations and Operator values.
        Added Precedence enum, and precedence function to all nodes. Removed
        nodeInsideAllParens. Added streamBinaryOperator function for serialization.
        Removed GroupNode and PropertyNameNode. Made PropertyNode store an Identifier.
        Removed FunctionCallParenBracketNode and FunctionCallParenDotNode.

        * kjs/nodes.cpp: Removed Node::nodinsideAllParens, GroupNode, and PropertyNameNode.
        (KJS::PropertyListNode::evaluate): Changed code to get name directly instead
        of converting it from an Identifier to a jsString then back to a UString
        then into an Identifier again!

        * kjs/nodes2string.cpp: Changed special-token implementation to use a separate
        function for each of Endl, Indent, Unindent, and DotExpr instead of using a
        single function with a switch. Added a precedence that you can stream in, to
        cause the next node serialized to add parentheses based on that precedence value.
        (KJS::operatorString): Moved to the top of the file.
        (KJS::escapeStringForPrettyPrinting): Moved here from function.cpp. Removed old
        workaround for snprintf, since StringExtras.h takes care of that.

        character append functions instead of constructing a UString. Added the logic

        - numerous HashTable performance improvements
        
        This does not quite add up to a measurable win on SunSpider, but it allows a
        follow-on > 3% improvement and probably helps WebCore too.
        
        I made the following improvements, among others:
        
        - Made HashFunctions note whether it is ok to compare a real value with the equal() function
        to the empty or deleted value, and used this to optimize the comparisons done in hash lookup.
        
        - Specialized lookup so it doesn't have to do so many extra branches and build so many extra
        std::pairs for cases that don't need them. There are now four versions, one for read-only access,
        two for writing, and one folded directly into add() (these all were improvments).
        
        - Made HashMap::get() use lookup() directly instead of find() to avoid having to build iterators.
        
        - Made a special constructor for iterators that knows it points to
        a valid filled cell and so skips updating itself.

        - Reordered memory accesses in the various lookup functions for better code generation
        
        - Made simple translators avoid passing a hash code around
        
        - Other minor tweaks

        Shrink the size of an activation object by 1 word
        
        This is in preparation for adding a symbol table to the activation 
        object.
        
        The basic strategy here is to rely on the mutual exclusion between
        the arguments object pointer and the function pointer (you only need
        the latter in order to create the former), and store them in the same 
        place. The LazyArgumentsObject class encapsulates this strategy.

        Change JavaScriptCore.vcproj to use DerivedSources.make

        We were trying to emulate the logic of make in
        build-generated-files.sh, but we got it wrong. We now use a
        build-generated-files very much like the one that WebCore uses to
        invoke make.

        We also now only have a Debug configuration of dftables which we build
        even when doing a Release build of JavaScriptCore. dftables also no
        longer has the "_debug" name suffix.

        Changes mostly made by Darin, reviewed by me.

        * DerivedSources.make: Add a variable to set the extension used for
        the dftables executable.
        * JavaScriptCore.vcproj/JavaScriptCore.sln: Updated to use Debug
        dftables in Release configurations.

           - Updated include path to point to the new location of the derived
             sources.
           - Modified pre-build event to pass the right arguments to
             build-generated-files.sh and not call dftables directly.
           - Added the derived source files to the project.
           - Removed grammarWrapper.cpp, which isn't needed now that we're
             compiling grammar.cpp directly.

        Moved processDeclarations call into FunctionBodyNode::execute

        To improve encapsulation, moved processDeclarations call into
        FunctionBodyNode::execute. Also marked processDeclarations 
        ALWAYS_INLINE, since it has only 1 caller now. This is a .71% speedup

        Re-structured variable and function declaration code.
        
        Command-line JS iBench shows no regression.
        
        Here are the changes:

        1. Function declarations are now processed at the same time as var 
        declarations -- namely, immediately upon entry to an execution context. 
        This does not match Firefox, which waits to process a function
        declaration until the declaration's containing block executes, but it 
        does match IE and the ECMA spec. (10.1.3 states that var and function 
        declarations should be processed at the same time -- namely, "On 
        entering an execution context." 12.2 states that "A Block does not 
        define a new execution scope.")

        2. Declaration processing proceeds iteratively now, rather than 
        recursively, storing the nodes is finds in stacks. This will later 
        facilitate an optimization to hold on to the gathered declaration nodes, 
        rather than re-fetching them in every function call.

        Removed surprising self-named "hack" that made nested functions 
        available as named properties of their containing functions, and placed
        containing function objects in the scope chains of nested functions.
        
        There were a few reasons to remove this "hack:"

        1. It contradicted FF, IE, and the ECMA spec.

        2. It incurred a performance penalty, since merely parsing a function 
        required parsing its body for nested functions (and so on).

        3. SVN history contains no explanation for why it was added. It was just
        legacy code in a large merge a long, long time ago.

        It fixes do-while statements to evaluate to a value. (They used
        to evaluate to the empty value in all cases.) 

        It also fixes SourceElementsNode to maintain the value of abnormal 
        completions like "break" and "continue."
        
        It also re-works the main execution loop in SourceElementsNode so that
        it (1) makes a little more sense and (2) avoids unnecessary work. This 
        is a .28% speedup on command-line JS iBench.

        * kjs/nodes.cpp:
        (DoWhileNode::execute):
        (SourceElementsNode::execute):
