  -----------
  [SCEV] Don't create SCEVPtrToAddr for unstable pointer representations. (#180718)

Conservatively treat unstable pointers as SCEVCouldNotCompute in
getPtrToAddrExpr, and return SCEVUnknown when constructing from IR.

This surfaced as part of the discussion in
https://github.com/llvm/llvm-project/pull/178861.
