[InstCombine] Handle "add like" in ADD+GEP->GEP+GEP rewrites (#135156)
Considering that "or disjoint" is the canonical for certain add
operations, then I think we want to support such "add like" operations
when doing ADD+GEP->GEP+GEP rewrites to make things more consistent.
Problem was found when improving ValueTracking, which turned an ADD into
OR, and then suddenly optimizations got worse due to these rewrites no
longer triggering.
