Actually, that could happen for several equivalent shuffles. Not in
this case though, because it's a really weird one. Right now, this
specific intrinsic can't match the 256-bit shufps instruction, because
the mask recognition isn't there yet (which is coming next w/ the
testcase), so it's emitting poor shuffles now.
