Keith Randall 3e270ab80b cmd/compile: clean up ctz ops ... Now that we have ops that can return 2 results, have BSF return a result and flags. We can then get rid of the redundant comparison and use CMOV instead of CMOVconst ops. Get rid of a bunch of the ops we don't use. Ctz{8,16}, plus all the Clzs, and CMOVNEs. I don't think we'll ever use them, and they would be easy to add back if needed.
