[SLP] allow matching integer min/max intrinsics as reduction ops
As noted in D98152, we need to patch SLP to avoid regressions when we start canonicalizing to integer min/max intrinsics. Most of the real work to make this possible was in: 7202f47508 Differential Revision: https://reviews.llvm.org/D98981
