Start cutting down `rustc_query_system` The query system is implemented in `rustc_query_system`, `rustc_middle`, and `rustc_query_impl`. `rustc_query_system` is hamstrung by not having access to `TyCtxt`, and there seems to be consensus to eliminate it. It's contents can be moved into the other two crates. Moving as much stuff as possible to `rustc_query_impl` is preferred, because `rustc_middle` is already so big. This PR starts this process. It moves one small function to `rustc_middle` and a good chunk of code to `rustc_query_impl`. Once `rustc_query_system` is gone (or at least shrunk down a lot more) some of the traits like `DepContext`, `QueryContext`, and `QueryDispatcher` will be removable. r? @Zalathar |
