Yingwei Zheng be2723da5c [InstSimplify] Fold icmp of X and/or C1 and X and/or C2 into constant (#65905) ...

This patch simplifies the pattern `icmp X and/or C1, X and/or C2` when
one constant mask is the subset of the other.
If `C1 & C2 == C1`, `A = X and/or C1`, `B = X and/or C2`, we can do the
following folds:
`icmp ule A, B -> true`
`icmp ugt A, B -> false`
We can apply similar folds for signed predicates when `C1` and `C2` are
the same sign:
`icmp sle A, B -> true`
`icmp sgt A, B -> false`

Fixes #65833.
