	Fixed <rdar://problem/3972522> (179-180) 40% slowdown on iBench JavaScript test

	I added a member variable to ObjectImp.  This changed it's size and consequently
	hampered the optimizations built into the garbage collector.  Objects no longer
	fit within the allocators cell size, and thus allocation fell back to a slower
	allocator.

	As a result of this fix I also dramatically cleaned up how runtime objects are
	accessed.  The path mostly *removes* code.
