  InstSimplify: support floating-point equivalences (#115152)

Since cd16b07 (IR: introduce CmpInst::isEquivalence), there is now an
isEquivalence routine in CmpInst that we can use to determine
equivalence in simplifySelectWithICmpEq. Implement this, extending the
code from integer-equalities to integer and floating-point equivalences.
