Tests look clean. Only change is a minor type ordering difference in a few error messages in RWC. |

10-run average from the original machine shows a 5% improvement. Very nice! |

This PR improves our reasoning about when to (and, more importantly, when not to) create deferred type references. We now create fewer deferred type references which improves overall compile times for the repro in #36566 by around 4%.
Fixes #36566.
