Made room for a free word in JSCell.

SunSpider says no change.

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in JSObject.h because they were often out of date, and they got in the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.
