[ConstraintElim] Simplify and/or instead of replacing its operand (#139874) ...

In `checkOrAndOpImpliedByOther`, replacing an operand of a disjoint or
is unsafe: https://alive2.llvm.org/ce/z/4R4hxN
This patch performs the simplification directly, to avoid miscompilation
and unnecessary canonicalization.

Closes https://github.com/llvm/llvm-project/issues/137937.
