Interesting but I would be a bit defensive and make sure that this
matches only if -ffast-math in the FP case. You are sort of relying on
the fact that vsub wouldn't be generated without ffast-math but I'd
rather be defensive about it . (This is in case it's not clear in the
non-intrinsics case)

Interesting but I would be a bit defensive and make sure that this
matches only if -ffast-ma
