Auto merge of #115864 - compiler-errors:rpitit-sugg, r=estebank
Suggest desugaring to return-position `impl Future` when an `async fn` in trait fails an auto trait bound First commit allows us to store the span of the `async` keyword in HIR. Second commit implements a suggestion to desugar an `async fn` to a return-position `impl Future` in trait to slightly improve the `Send` situation being discussed in #115822. This suggestion is only made when `#![feature(return_type_notation)]` is not enabled -- if it is, we should instead suggest an appropriate where-clause bound.
