Which target actually uses the [(operation) (set (cc) ...)] order in their
*.md patterns? Even aarch64 and arm use the [(set (cc) ...) (operation)]
order that combine expects, I thought compare-elim was written for those
targets? If the vast majority of mds use the order that combine expects,
I think it should be easier to adjust compare-elim.c and those few targets
that diverge.
