[x86] swap order of srl (and X, C1), C2 when it saves size The (non-)obvious win comes from saving 3 bytes by using the 0x83 'and' opcode variant instead of 0x81. There are also better improvements based on known-bits that allow us to eliminate the mask entirely. As noted, this could be extended. There are potentially other wins from always shifting first, but doing that reveals a tangle of problems in other pattern matching. We do this transform generically in instcombine, but we often have icmp IR that doesn't match that pattern, so we must account for this in the backend.
