  [InstCombine] Support logical ops in foldAndOrOfICmpsWithConstEq() (NFC)

This is largely just for the sake of completeness. For logical ops,
this is mostly subsumed by foldSelectValueEquivalence() in a more
generic way. The only exception is vector support, as select
value equivalence folding currently doesn't support this for the
case where the replacement does not simplify.
