Without `-stop-after`, how are folks expected to test SelectionDAG in isolation?

(`-stop-before` is the other side of the same coin as `-stop-after` for whatever pass comes before finalize-isel. It's asymmetric to support one without the other, but if I can only have one, that's good enough to do my job).
