  Log Message:
  -----------
  [Analysis] propagate poison through integer min/max intrinsics

A more general enhancement needs to add tests and make sure
that intrinsics that return structs are correct. There are also
target-specific intrinsics, and I'm not sure what behavior is
expected for those.
