fitzgen labeled issue #4961:

A not-insignificant portion of compilation time is spent in lowering, and when you start expanding the call tree, a lot of that time semi-surprisingly ends up being in value_def. value_def ends up doing repeated alias resolution, my theory is that we are repeatedly doing overlapping alias resolutions. We should investigate using union find to incrementally dedupe this repeated work.

The cache for this would need to be cleared when changing the definition of any alias, right?
