Use SCEVPtrToAddr instead of SCEVPtrToInt for pointer -> int conversion in SCEV, like when computing trip count expressions. getPtrToIntExpr now also creates SCEVPtrToAddrExpr. Removal of SCEVPtrToIntExpr out of this PR, to limit the scope and will be done as NFC follow-up. PR: https://github.com/llvm/llvm-project/pull/180244
