The UNLIKELY() macro buys us nothing here anyway so we should probably kill off our use of it. Though I'm all for surgical uses of UNLIKELY() in places where it matters, I don't like using it in places where we know it does nothing.
As well, JSArray.cpp has one place where it does the same test but by comparing directly against 0xFFFFFFFF. It should really be comparing against MAX_ARRAY_INDEX.
