The `_Concurrency` and `_StringProcessing` modules are implementation details of the standard library; to developers, their contents should behave as though they are declared directly within module `Swift`. This is the exact same behavior we expect of cross-import overlays, so treat these modules as though they are cross-import overlays with no bystanding module. Because these modules don’t re-export the standard library, it’s also necessary to treat `Swift` as a separately imported overlay of itself; do so and make that actually work.
