Reimplement the bittest intrinsic family as builtins with inline asm

We need to implement _interlockedbittestandset as a builtin for
windows.h, so we might as well do the whole family. It reduces code
duplication anyway.

Fixes PR33188, a long standing bug in our bittest implementation
encountered by Chakra.
