SHA1H instructions may be scheduled after a SHA1C instruction that uses the same input register.
SHA1H instructions may be scheduled after a SHA1C instruction
that uses the same input register. However SHA1C updates its input,
so if SHA1H is scheduled after it, it requires an extra move.
Increase the priority of SHA1H to ensure it gets scheduled
earlier, avoiding the move.
