This is admittedly a narrow fix for the problem: https://bugs.llvm.org/show_bug.cgi?id=37502 ...but as the XOP restriction shows, it's a maze to get this right. In the motivating example, note that we have movddup before SSE4.1 and again with AVX2. That's because insertps isn't available pre-SSE41 and vbroadcast is (more generally) available with AVX2 (and the splat is reduced to movddup via isel pattern).
