        Stop loading constants into the register file.

        Instead, use high register values (highest bit bar the sign bit set) to indicate
        constants in the instruction stream, and when we encounter such a value load it
        directly from the CodeBlock.

        Since constants are no longer copied into the register file, this patch renders
        the 'unexpected constant' mechanism redundant, and removes it.

        Bug 27025: Crashes and regression test failures related to regexps in 64-bit

        For x86_64 RegexGenerator uses rbx, a callee-save register, as a scratch register but
        neglects to save and restore it.  The change in handling of the output vector in r45545
        altered code generation so that the RegExp::match was now storing important data in rbx,
        which caused crashes and bogus results when it was clobbered.

        Fix run-time crashes in JavaScriptCore with the Metrowerks compiler on Symbian.

        The Metrowerks compiler on the Symbian platform moves the globally
        defined Hashtables into read-only memory, despite one of the members
        being mutable. This causes crashes at run-time due to write access to
        read-only memory.

        Avoid the use of const with this compiler by introducing the
        JSC_CONST_HASHTABLE macro.

        Override operator new/delete with const std::nothrow_t& as the second

        On Windows CE, operator new/delete, new[]/delete[] with const
        std::nothrow_t& must be overrided because some standard template
        libraries use these operators.

        The problem occurs when memory allocated by new(size_t s, const
        std::nothrow_t&) is freed by delete(void* p). This causes the umatched
        malloc/free problem.

        fastMaloc and fastFree consistently.

        The BytecodeGenerator objects were instantiated on stack, which takes up ~38kB per instance
        (each instance includes copy of JSC::CodeBlock with large SymbolTable, etc.).
        Specifically, since there is nested invocation (e.g., GlobalCode --> FunctionCode),
        the stack overflows immediately on Symbian hardware (max. 80 kB).
        Proposed change allocates generator objects on heap.
        Performance impact (if any) should be negligible and change is proposed as general fix,
        rather than ifdef'd for SYMBIAN.

        Fix stupid performance problem in the LiteralParser

        The LiteralParser was making a new UString in order to use
        toDouble, however UString's toDouble allows a much wider range
        of numberic strings than the LiteralParser accepts, and requires
        an additional heap allocation or two for the construciton of the
        UString.  To rectify this we just call WTF::dtoa directly using

        We need to make sure that each native function instance correctly unlinks any references to it

              so we no longer get to have a single shared instance.

        Timezone calculation incorrect in Venezuela.

        <rdar://problem/6646169> Time is incorrectly reported to JavaScript in both Safari 3 and Firefox 3

        The problem is that we're calculating the timezone relative to 01/01/2000,
        but the VET timezone changed from -4 hours to -4:30 hours on 12/09/2007.
        According to the spec, section 15.9.1.9 states "the time since the beginning
        of the year", presumably meaning the *current* year.  Change the calculation
        to be based on whatever the current year is, rather than a canned date.

        No performance impact.

        Change the implementation of op_throw so the stub function always modifies its
        return address - if it doesn't find a 'catch' it will switch to a trampoline
        to force a return from JIT execution.  This saves memory, by avoiding the need
        for a unique return for every op_throw.

        Bug 26429: Make JSON.stringify non-recursive so it can handle objects
        of arbitrary complexity
        https://bugs.webkit.org/show_bug.cgi?id=26429

        For marking I decided not to use gcProtect, because this is inside the engine
        so it's easy enough to just do marking. And that darned gcProtect does locking!
        Oliver tried to convince me to used MarkedArgumentBuffer, but the constructor
        for that class says "FIXME: Remove all clients of this API, then remove this API."

        * runtime/Collector.cpp:
        (JSC::Heap::collect): Add a call to JSONObject::markStringifiers.

        * runtime/CommonIdentifiers.cpp:
        (JSC::CommonIdentifiers::CommonIdentifiers): Added emptyIdentifier.

        (JSC::unwrapNumberOrString): Added. Helper for unwrapping number and string
        objects to get their number and string values.
        (JSC::ReplacerPropertyName::ReplacerPropertyName): Added. The class is used
        to wrap an identifier or integer so we don't have to do any work unless we
        actually call a replacer.
        (JSC::ReplacerPropertyName::value): Added.
        (JSC::gap): Added. Helper function for the Stringifier constructor.
        (JSC::PropertyNameForFunctionCall::PropertyNameForFunctionCall): Added.
        The class is used to wrap an identifier or integer so we don't have to

        (JSC::PropertyNameForFunctionCall::asJSValue): Added.
        (JSC::Stringifier::Stringifier): Updated and moved out of the class
        definition. Added code to hook this into a singly linked list for marking.
        (JSC::Stringifier::~Stringifier): Remove from the singly linked list.
        (JSC::Stringifier::mark): Mark all the objects in the holder stacks.
        (JSC::Stringifier::stringify): Updated.

        (JSC::Stringifier::toJSON): Renamed from toJSONValue.
        (JSC::Stringifier::appendStringifiedValue): Renamed from stringify.
        Added code to use the m_holderStack to do non-recursive stringify of
        objects and arrays. This code also uses the timeout checker since in
        pathological cases it could be slow even without calling into the
        JavaScript virtual machine.

        (JSC::Stringifier::Holder::appendNextProperty): Added. This is the
        function that handles the format of arrays and objects.
        (JSC::JSONObject::getOwnPropertySlot): Moved this down to the bottom
        of the file so the JSONObject class is not interleaved with the
        Stringifier class.
        (JSC::JSONObject::markStringifiers): Added. Calls mark.
        (JSC::JSONProtoFuncStringify): Streamlined the code here. The code
