        Remove debug-specific def file.
        Only Debug_All target uses JavaScriptCore_debug.dll naming, and since

        dictionary, but instead we want un-dictionary heavily accessed
        prototypes; (2) It folded a test for hasDefaultGetPropertyNames() into
        a generic test for "cacheable-ness", but hasDefaultGetPropertyNames()
        is only releavant to for-in caching.

        Eliminated some legacy bytecode weirdness.
        
        Use vPC[x] subscripting instead of ++vPC to access instruction operands.
        This is simpler, and often more efficient.

        To support this, and to remove use of hard-coded offsets in bytecode and
        JIT code generation and dumping, calculate jump offsets from the beginning
        of an instruction, rather than the middle or end.
        
        Also, use OPCODE_LENGTH instead of hard-coded constants for the sizes of
        opcodes.
        
        SunSpider reports no change in JIT mode, and a 1.01x speedup in Interpreter
        mode.

        [Qt] Assert messages prints visible in Symbian
        https://bugs.webkit.org/show_bug.cgi?id=29808

        Asserts use vprintf to print the messages to stderr.

        https://bugs.webkit.org/show_bug.cgi?id=29695

        On ARMv5 and below all data access should be naturally aligned.
        In the YARR_JIT there is a case when character pairs are
        loaded from the input string, but this data access is not
        naturally aligned. This fix introduces load32WithUnalignedHalfWords

        SNES is too slow
        https://bugs.webkit.org/show_bug.cgi?id=29534

        The problem was that the emulator used multiple classes with
        more properties than our dictionary cutoff allowed, this resulted
        in more or less all critical logic inside the emulator requiring
        uncached property access.

        Rather than simply bumping the dictionary cutoff, this patch
        recognises that there are two ways to create a "dictionary"
        structure.  Either by adding a large number of properties, or
        by removing a property.  In the case of adding properties we
        know all the existing properties will maintain their existing
        offsets, so we could cache access to those properties, if we
        know they won't be removed.

        To make this possible, this patch adds the logic required to
        distinguish a dictionary created by addition from one created
        by removal.  With this logic in place we can now cache access
        to objects with large numbers of properties.

        SNES performance improved by more than 6x.

        Implement ES5 Object.defineProperty function
        https://bugs.webkit.org/show_bug.cgi?id=29503

        Implement Object.defineProperty.  This requires adding the API to
        ObjectConstructor, along with a helper function that implements the
        ES5 internal [[ToPropertyDescriptor]] function.  It then adds
        JSObject::defineOwnProperty that implements the appropriate ES5 semantics.
        Currently defineOwnProperty uses a delete followed by a put to redefine
        attributes of a property, clearly this is less efficient than it could be
        but we can improve this if it needs to be possible in future.

        Symbian compiler for emulator target (WINSCW) fails with
        "illegal operand" for m_attributesInPrevious in structure.ccp
        (when calling make_pair functions).
        This error is apparently due to the compiler not properly

        Initial patch explicitly casted m_attributesInPrevious
        to unsigned, but since bitfield optimization is not critical for

        [Qt] Fix wtf/ThreadSpecific.h under Qt to free thread local objects.
        https://bugs.webkit.org/show_bug.cgi?id=29295

        This is an important fix when JavaScript workers are in use, since
        unfreed ThreadGlobalDatas leak a big amount of memory (50-100k each).
        QThreadStorage calls the destructor of a given object, which is the
        ThreadSpecific::Data. Unlike pthread, Qt is object oriented, and does
        not support the calling of a static utility function when the thread
        is about to close. In this patch we call the ThreadSpecific::destroy()
        utility function from the destructor of ThreadSpecific::Data. Moreover,
        since Qt resets all thread local values to 0 before the calling of the
        appropriate destructors, we set back the pointer to its original value.
        This is necessary because the get() method of the ThreadSpecific
        object may be called during the exuction of the destructor.

        Allow anonymous storage inside JSObject
        https://bugs.webkit.org/show_bug.cgi?id=29168

        Add the concept of anonymous slots to Structures so that it is
        possible to store references to values that need marking in the
        standard JSObject storage buffer.  This allows us to reduce the
        malloc overhead of some objects (by allowing them to store JS
        values in the inline storage of the object) and reduce the 
        dependence of custom mark functions (if all an objects children
        are in the standard object property storage there's no need to
        mark them manually).
