        I changed JSCallbackObjectData, Arguments, JSArray, and RegExpObject to
        store auxiliary data in a secondary structure.

        I changed InternalFunction to store the function's name in the property
        map.
        
        I changed JSGlobalObjectData to use a virtual destructor, so WebCore's
        JSDOMWindowBaseData could inherit from it safely. (It's a strange design
        for JSDOMWindowBase to allocate an object that JSGlobalObject deletes,
        but that's really our only option, given the size constraint.)
        
        I also added a bunch of compile-time ASSERTs, and removed lots of comments
        in JSObject.h because they were often out of date, and they got in the
        way of reading what was actually going on.
        
        Also renamed JSArray::getLength to JSArray::length, to match our style
        guidelines.

        Changed JSDOMWindowBase to store its auxiliary data in a subclass of
        JSGlobalData, so the two could share a pointer.
        
        Added a bunch of ASSERTs, to help catch over-sized objects.
