Reimplementation of FunctionStub to avoid rewriting potentially executing code for a slight improvement in thread safety.
Make VTABLE patching treadsafe to the extent possible. As-is it's now safe against itself running on other threads at lease, as well as against other similar implementations, though the inherent VM operation race is resolved by retrying.
BUG=27415
TEST=Included unittests.
