[X86] Use shufflevector instead of a select with a constant mask for fmaddsub/fmsubadd IR emission.
Shufflevector is easier to generate and matches what the backend pattern matches without relying on constant selects being turned into shuffles.
While I was there I also made the IR regular expressions a little stricter to ensure operand order on the shuffle.
