This catches many cases where we can emit a more efficient shuffle for a specific mask or when the mask contains undefs. Once the splat is lowered to unpacks we can't do that anymore. There is a possibility of moving the promotion after pshufb matching, but I'm not sure if pshufb with a mask loaded from memory is faster than 3 shuffles, so I avoided that for now. llvm-svn: 173569
