Comment (by osa1):

 Almost done ... I removed the entire cross-DLL stuff, with a lot of other
 comments and code, and it validates. As said in comment:27 I think the DLL
 stuff
 is not relevant to the task (we don't do any cross-module stuff), and the
 function (`rhsIsStatic`) is not used elsewhere, so it's fine to remove it.

 I need to do some refactoring, and `ModIface` updates are currently
 terrible
 because the `ModIface` type is not easy to update (holds everything in
 lists).
 Another problem is I introduced new Stg passes. I'll do some refactoring
 and
 then submit a diff to get some comments before doing more refactoring to
 fix
 these issues.
