These instructions weren't in the initial version of MMX, but were added when SSE1 was introduced. We already have the intrinsic named correctly to include sse and the frontened header enforces sse. We have one place in the backend where we DAG combine to this intrinsic, but that's also qualified. So don't know of anything currently broken unless someone writes their own IR and doesn't set the sse feature.
