        Added workaround for the limitation that VirtualFree with MEM_RELEASE
        can only accept the base address returned by VirtualAlloc when the region
        was reserved and it can only free the entire region, and not a part of it.

        Stack overflow crash in JavaScript garbage collector mark pass
        https://bugs.webkit.org/show_bug.cgi?id=12216

        Make the GC mark phase iterative by using an explicit mark stack.
        To do this marking any single object is performed in multiple stages
          * The object is appended to the MarkStack, this sets the marked
            bit for the object using the new markDirect() function, and then
            returns
          * When the MarkStack is drain()ed the object is popped off the stack
            and markChildren(MarkStack&) is called on the object to collect 
            all of its children.  drain() then repeats until the stack is empty.

        Additionally I renamed a number of methods from 'mark' to 'markAggregate'
        in order to make it more clear that marking of those object was not
        going to result in an actual recursive mark.

        1) The support for nothrow was inside #if PLATFORM(WINCE) even though it is

        2) The code tried to override operator delete nothrow, which does not exist.

        JSON.stringify replacer returning undefined does not omit object properties
        https://bugs.webkit.org/show_bug.cgi?id=28118

        Correct behaviour of stringify when using a replacer function that returns
        undefined.  This is a simple change to move the undefined value check to
        after the replacer function is called.  This means that the replacer function
        is now called for properties with the value undefined, however i've confirmed
        that this behaviour is correct.
        
        In addition I've made the cyclic object exception have a more useful error
        message.
