    cmd/compile: clean up ctz ops · 3e270ab8
    Keith Randall authored
    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.
