[InstCombine] Canonicalize `icmp pred (X +/- C1), C2` into `icmp pred X, C2 -/+ C1` with nowrap flag implied by with.overflow intrinsic (#75511)
This patch tries to canonicalize the pattern `Overflow | icmp pred Res,
C2` into `Overflow | icmp pred X, C2 +/- C1`, where `Overflow` and `Res`
are return values of `xxx.with.overflow X, C1`.
