    M llvm/test/Transforms/InstSimplify/or-icmps-same-ops.ll

  Log Message:
  [InstSimplify] use isImpliedCondition() instead of semi-duplicated code

We get a couple of improvements from recognizing swapped
operand patterns that were not handled by the replicated

This should also enable simplifying larger patterns as
seen in issue #56653 and issue #56654, but that requires
enhancements to isImpliedCondition() itself.
