DescriptionMerged r11831 into trunk branch.
Revert part of 11727 as it sometimes tanked V8 benchmark (raytrace) performance for reasons that are not obvious. Now we make objects into fast-case objects when they are made prototypes for other objects, but we do not mark objects that are already fast case with a bit that helps keep them in fast case.
