Owen Anderson e84178a0bd Extend SimplifyCFG's common-destination folding heuristic to allow a single ...

"bonus" instruction to be speculatively executed.  Add a heuristic to
ensure we're not tripping up out-of-order execution by checking that this bonus
instruction only uses values that were already guaranteed to be available.

This allows us to eliminate the short circuit in (x&1)&&(x&2).
