default binding modes: add pat_binding_modes
This PR kicks off the implementation of the [default binding modes RFC][1] by introducing the `pat_binding_modes` typeck table mentioned in the [mentoring instructions][2]. `pat_binding_modes` is populated in `librustc_typeck/check/_match.rs` and used wherever the HIR would be scraped prior to this PR. Unfortunately, one blemish, namely a two callers to `contains_explicit_ref_binding`, remains. This will likely have to be removed when the second part of [1], the `pat_adjustments` table, is tackled. Appropriate comments have been added. See #42640. [1]: https://github.com/rust-lang/rfcs/pull/2005 [2]: https://github.com/rust-lang/rust/issues/42640#issuecomment-313535089
