This is an alternative to D37896. I don't see a way to decompose multiplies generically without a target hook to tell us when it's profitable. ARM and AArch64 may be able to remove some duplicate code that overlaps with this transform. As a first step, we're only getting the most clear wins on the vector examples requested in PR34474: https://bugs.llvm.org/show_bug.cgi?id=34474 As noted in the code comment, it's likely that the x86 constraints are tighter than necessary, but it may not always be a win to replace a pmullw/pmulld.
