Collect deeply nested type names in alias analysis

Browse source 
Previously we only collected type names that appeared on the surface of
a type during alias analysis, but certain types that need to be named
(i.e. recursive types) may be observed only when we actually convert the IR
to the morphic IR. Make sure we collect those appropriately.

This is a cherry pick of the relevant changes in #4121.
