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.

PLT speedup related to <rdar://problem/5659272> REGRESSION: PLT .4%
slower due to r28884 (global variable symbol table optimization)
Geoff's theory is that the slowdown was due to copying hash tables when
putting things into the back/forward cache. If that's true, then this
should fix the problem.
(According to Geoff's measurements, in a PLT that exaggerates the
importance of symbol table saving during cached page creation, this
patch is a ~3X speedup in cached page creation, and a 9% speedup overall.)
* JavaScriptCore.exp: Updated.
* kjs/JSVariableObject.cpp:
(KJS::JSVariableObject::saveLocalStorage): Updated for changes to SavedProperty,
which has been revised to avoid initializing each SavedProperty twice when building
the array. Store the property names too, so we don't have to store the symbol table
separately. Do this by iterating the symbol table instead of the local storage vector.
(KJS::JSVariableObject::restoreLocalStorage): Ditto. Restore the symbol table as
well as the local storage vector.
* kjs/JSVariableObject.h: Removed save/restoreSymbolTable and do that work inside
save/restoreLocalStorage instead. Made restoreLocalStorage a non-const member function
that takes a const reference to a SavedProperties object.
* kjs/LocalStorage.h: Changed attributes to be unsigned instead of int to match
other declarations of attributes elsewhere.
* kjs/property_map.cpp:
(KJS::SavedProperties::SavedProperties): Updated for data member name change.
(KJS::PropertyMap::save): Updated for data member name change and to use the new
inline init function instead of setting the fields directly. This allows us to
skip initializing the SavedProperty objects when first allocating the array, and
just do it when we're actually setting up the individual elements.
(KJS::PropertyMap::restore): Updated for SavedProperty changes.
* kjs/property_map.h: Changed SavedProperty from a struct to a class. Set it up so
it does not get initialized at construction time to avoid initializing twice when
creating an array of SavedProperty. Removed the m_ prefixes from the members of
the SavedProperties struct. Generally we use m_ for class members and not struct.

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.

did the same with all data members. Renamed m_thisVal to m_thisValue and

Bug 17001: Build error with Gtk port on Mac OS X
If both XP_MACOSX and XP_UNIX are defined then X11.h and Carbon.h will both be included.
These provide conflicting definitions for a type named 'Cursor'. As XP_UNIX is set by
the build system when targeting X11, it doesn't make sense for XP_MACOSX to also be set
in this instance.

Reworked the JavaScriptCore Qt bindings:
* Add initial support for string and variant arrays, as well
as sub QObjects in the JS bindings.
* Don't expose fields marked as not scriptable by moc.
* Add support for dynamic properties and accessing named
QObject children of an object (like QtScript and older
IE DOM style JS).
* Add support for custom toString methods.
* Fine tune some bindings to be closer to QtScript.
Make void functions return undefined, and empty/
null QStrings return a zero length string.
* Create framework for allowing more direct method calls.
Since RuntimeMethod doesn't allow us to add additional
methods/properties to a function, add these classes.
Start prototyping object.signal.connect(...).
* Add signal support to the Qt bindings.
Allow connecting to signals (object.signal.connect(slot)),
disconnecting, and emitting signals. Currently chooses
the first signal that matches the name, so this will need
improvement.
* Add property names, and resolve signals closer to use.
Enumerating properties now returns some of the Qt properties
and signals. Slots and methods aren't quite present. Also,
resolve signal connections etc. closer to the time of use, so
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.

To match Firefox, we've decided that var declarations will never shadow

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
marked inline, and called in exactly one place, so moved it there.
No idea why it was in this header file!
* kjs/scope_chain.cpp: Removed the overload of the ScopeChain::push
function that takes another ScopeChain. It was unused. I think we used
it over in WebCore at one point, but not any more.
* 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.

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:

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

REGRESSION (r28525): regular expression tests failing due to bad firstByte optimization
* pcre/pcre_compile.cpp: Changed some names to use interCaps intead of under_scores.
(branchIsAnchored): Broke is_anchored into two separate functions; this one works on a
branch and the other on an anchor. The old function would only work on a bracket.
Also removed unneeded parameters; the anchored check does not require the bracket
map or the options any more because we have a reduced set of features.
(bracketIsAnchored): Ditto.
(branchNeedsLineStart): Broke canApplyFirstCharOptimization into two functions and gave
both a better name. This is the function that was returning the wrong value. The failure
was beacuse the old function would only work on a bracket.
(bracketNeedsLineStart): Ditto.
(jsRegExpCompile): Changed to call the appropriate branch or bracket flavor of the
functions based on whether we compiled an outer bracket. Also removed inaccurate comments
and unneeded parameters.

* pcre/pcre.h: Renumbered error codes, in a logical order. First, normal failure, then
the recursion limit, then running out of memory, and finally an unexpected internal error.

Another round of grammar / parsing cleanup.
1. Created distinct parser calls for parsing function bodies vs
programs. This will help later with optimizing global variable access.
2. Turned Parser into a singleton. Cleaned up Lexer's singleton
interface.
3. Modified Lexer to free a little more memory when done lexing. (Added
FIXMEs for similar issues that I didn't fix.)
4. Changed Lexer::makeIdentifier and Lexer::makeUString to start
respecting the arguments passed to them. (No behavior change, but this
problem could have caused serious problems for an unsuspecting user of
these functions.)
5. Removed KJS_DEBUG_MEM because it was bit-rotted.
6. Removed Parser::prettyPrint because the same work was simpler to do
at the call site.
7. Some renames:
"Parser::accept" => "Parser::didFinishParsing"

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.

- 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.
* JavaScriptCore.exp: Updated for new entry points.
* JavaScriptCore.pri:
* JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.vcproj:
* JavaScriptCore.vcproj/dftables/dftables.vcproj:
* JavaScriptCore.xcodeproj/project.pbxproj:
* JavaScriptCoreSources.bkl:
* jscore.bkl:
Updated for new source file names and ForwardingHeaders.
* kjs/regexp.cpp:
(KJS::RegExp::RegExp): Changed to use the error message without calling
strdup on it and to pass the new types and options.
(KJS::RegExp::~RegExp): Removed the now-unneeded free of the error message.
(KJS::RegExp::match): Pass the new types and options.
* kjs/regexp.h: Update type of m_constructionError.
* pcre/AUTHORS: Update to reflect the status of the project -- we don't include
the Google parts, and this isn't the PCRE library, per se.
* pcre/COPYING: Ditto.
* pcre/dftables.cpp: Copied from JavaScriptCore/pcre/dftables.c.
(main): Removed unneeded ctype_digit.
* pcre/pcre.h: Convert to C++, tweak API a bit. Use UChar instead of JSRegExpChar.
* pcre/pcre_compile.cpp: Copied from JavaScriptCore/pcre/pcre_compile.c.
Moved a lot of private stuff used only within this file here from pcre_internal.h.
Renumbered the error codes.
(error_text): Use a single string with embedded nulls for the error text (I got
this idea from newer versions of PCRE).
(check_escape): Changed return type to be enum instead of int. Replaced ctype_digit
uses with isASCIIDigit.
(is_counted_repeat): Ditto.
(read_repeat_counts): Ditto.
(first_significant_code): Ditto.
(find_fixedlength): Ditto.
(could_be_empty_branch): Ditto.

(compile_regex): Updated for change to options parameter.
(is_anchored): Ditto.
(find_firstassertedchar): Ditto.
(jsRegExpCompile): Changed to take separate flags instead of an options int.
Also changed to call new/delete instead of pcre_malloc/free.
(jsRegExpFree): Ditto.
* 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
in -- it's only used for dftables now (and soon may be obsolete entirely).
Changed code for cbit_digit to not use isdigit, and took the "_" case out of the
loop. Removed ctype_digit.
* pcre/pcre_ord2utf8.cpp: Copied from JavaScriptCore/pcre/pcre_ord2utf8.c.
* pcre/pcre_tables.cpp: Copied from JavaScriptCore/pcre/pcre_tables.c.

* pcre/ucpinternal.h: Updated header.
* pcre/ucptable.cpp: Copied from JavaScriptCore/pcre/ucptable.c.
* wtf/ASCIICType.h: (WTF::isASCIIDigit): Removed a branch by changing from && to
& for this operation. Also added an overload that takes an int because that's
useful for PCRE. Later we could optimize for int and overload other functions in
this file; stuck to this simple one for now.

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

Speeds up string-base64 30%, and at least 0.5% overall.

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
any other tests.

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.
SunSpider claims this is a 1.0% speedup.

exact same thing. Moved the handling of opcodes higher than OP_BRA into the default

branch from each iteration of the opcode interpreter, just as removal of "op"

make some even more significant changes to the regexp engine

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.

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

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.

Much supporting work done by Maciej Stachowiak, Maks Orlovich, and
Cameron Zwarich.
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
that the fast path is impossible, to make sure we didn't leave anything
on the table.
(KJS::FunctionBodyNode::optimizeResolveNodes): Here's where the AST

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.

workaround for snprintf, since StringExtras.h takes care of that.

- 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

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.
Also inlined the ArgumentsImp constructor, for good measure.

Merged DeclaredFunctionImp into FunctionImp (the base class) because
the distinction between the two was unused.
Removed codeType() from FunctionImp because FunctionImp and its
subclasses all returned FunctionCode, so it was unused, practically
speaking.
Removed a different codeType() from GlobalFuncImp because it was unused.

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.

1. Added shrink(), which is a version of resize() that you can call
to save a branch / improve code generation and inlining when you know
that the vector is not getting bigger.
2. Changed subclassing relationship in VectorBuffer to remove a call to
fastFree() in the destructor for the inlineCapacity != 0 template
specialization. This brings inline Vectors one step closer to true
stack-allocated arrays.
Also changed abort() to CRASH(), since the latter works better.

[ Broken off from http://bugs.webkit.org/show_bug.cgi?id=14868 ]
This patch is a merge of KDE r670547, with substantial modification
for performance.
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.
