  InstCombine: support floating-point equivalences (#114975)

Since cd16b07 (IR: introduce CmpInst::isEquivalence), there is now an
isEquivalence routine in CmpInst that we can use to determine
equivalence in foldSelectValueEquivalence. Implement this, extending it
to include floating-point equivalences as well.
