  [PhaseOrdering] Add test for PR39282 (NFC)

While the actually incorrect transform happens in LoopUnroll, it
is based on noalias metadata inserted by the inliner, and
ultimately manifests in GVN. Add a phase ordering test that checks
this even if our representation of noalias metadata changes in
the future.
