It looks correct, but it doesn't seem very general... there should
really just be a generic DecomposeMERGE_VALUES usable from every
handler that just has a single "ReplaceValueWith(SDValue(N, i),
SDValue(N->getOperand(i)));" loop.  (Long-term, we really should just
get rid of MERGE_VALUES, but it's a substantial amount of work.)
