Still a WIP, but might be get some feedback on the direction.

I'm not 100% sure when to consider a search path that triggered the creation of `Module` as used. Doing so on `Module` creation is not useful, since we do that (somewhat) eagerly. The current approach marks search path as used whenever it's responsible for the creation of a `Module` that gets returned by `HeaderSearch::lookupModule`. That's not correct in situations when a `Module` is created via header search (but not actually returned) and then gets queried directly from `ModuleMap` instead of `HeaderSearch`.
