--- Comment #2 from ktkachov at gcc dot gnu.org ---
Allowing -(cast)CMP works well.
Adding (cast)CMP unconditionally regresses some tree-ssa.exp tests:
ssa-ifcombine-ccmp-6, fold-xor-and-or, fold-xor-or, if-to-switch-9, pr20701,
pr21090, vrp33, vrp102, pr68198.
We can avoid those though if we do this only when every use of the PHI result
is an equality or inequality test against an integer constant
