[InstComb] Allow more user for (add (ptrtoint %B), %O) to GEP transform. (#153566) ...

Generalize the logic from
https://github.com/llvm/llvm-project/pull/153421 to support additional
cases where the pointer is only used as integer.

Alive2 Proof: https://alive2.llvm.org/ce/z/po58pP

This enables vectorizing std::find for some cases, if additional
assumptions are provided: https://godbolt.org/z/94oq3576E

Depends on https://github.com/llvm/llvm-project/pull/15342.
