The invalid suggestion came from a wrongly created span in `rustc_parse' for closure arguments that didn't have a type specified. Specifically, the span in this case was the last token span, but in the case of tuples, the span represented the last parenthesis instead of the whole tuple, which is fixed by taking the more accurate span of the pattern.

merge functionality of `io::Sink` into `io::Empty` Many times, there is a need for a simple dummy `io::Read`er + `io::Write`r, but currently the only options are `io::Empty` and `io::Sink` respectively. Having both of their functionality together requires writing your own boilerplate for something that makes sense to have in the standard library. This PR adds the functionality of `io::Sink` to `io::Empty`, making `io::Empty` be able to perform the tasks of both of the previous structs. (This idea was first mentioned in rust-lang#24235) Note: I also updated some doc comments in `io::utils` in this pull request to fix inconsistencies between `io::Sink` and `io::Empty`. API Change Proposal: rust-lang/libs-team#49

`const`-stablilize `NonNull::as_ref` A bunch of pointer to reference methods have been made unstably const some time ago in rust-lang#91823 under the feature gate `const_ptr_as_ref`. Out of these, `NonNull::as_ref` can be implemented as a `const fn` in stable rust today, so i hereby propose to const stabilize this function only.

…pkin Fix invalid suggestion for mismatched types in closure arguments This PR fixes the invalid suggestion for mismatched types in closure arguments. The invalid suggestion came from a wrongly created span in the parser for closure arguments that don't have a type specified. Specifically, the span in this case was the last token span, but in the case of tuples, the span represented the last parenthesis instead of the whole tuple, which is fixed by taking the more accurate span of the pattern. There is one unfortunate downside of this fix, it worsens even more the diagnostic for mismatched types in closure args without an explicit type. This happens because there is no correct span for implied inferred type. I tried also fixing this but it's a rabbit hole. Fixes rust-lang#114180
