Add lang items for `AsyncFn*`, `Future`, `AsyncFnKindHelper`'s associated types Adds lang items for `AsyncFnOnce::Output`, `AsyncFnOnce::CallOnceFuture`, `AsyncFnMut::CallRefFuture`, and uses them in the new solver. I'm mostly interested in doing this to help accelerate uplifting the new trait solver into a separate crate. The old solver is kind of spaghetti, so I haven't moved that to use these lang items (i.e. it still uses `item_name`-based comparisons). update: Also adds lang items for `Future::Output` and `AsyncFnKindHelper::Upvars`. cc ``@lcnr`` |
