To get rid of the `Ident::empty` uses. This requires introducing `PathParser::word_sym`, as an alternative to `PathParser::word`.
By using `@` patterns more. Also, use `Symbol` more in a couple of errors to avoid some unnecessary conversions to strings. This even removes a lifetime.

…onszelmann Eliminate `word_and_empty` methods. To remove the last remaining `Ident::empty` uses. r? ``@jdonszelmann``
…ulacrum Clarify black_box warning a bit Trying to bring the docs on black_box more in line with the advice that we have discussed in Zulip. rust-lang#140341 (comment)
… r=lcnr Only include `dyn Trait<Assoc = ...>` associated type bounds for `Self: Sized` associated types if they are provided Since rust-lang#136458, we began filtering out associated types with `Self: Sized` bounds when constructing the list of associated type bounds to put into our `dyn Trait` types. For example, given: ```rust trait Trait { type Assoc where Self: Sized; } ``` After rust-lang#136458, even if a user writes `dyn Trait<Assoc = ()>`, the lowered ty would have an empty projection list, and thus be equivalent to `dyn Trait`. However, this has the side effect of no longer constraining any types in the RHS of `Assoc = ...`, not implying any WF implied bounds, and not requiring that they hold when unsizing. After this PR, we include these bounds, but (still) do not require that they are provided. If the are not provided, they are skipped from the projections list. This results in `dyn Trait` types that have differing numbers of projection bounds. This will lead to re-introducing type mismatches e.g. between `dyn Trait` and `dyn Trait<Assoc = ()>`. However, this is expected and doesn't suffer from any of the deduplication unsoundness from before rust-lang#136458. We may want to begin to ignore thse bounds in the future by bumping `unused_associated_type_bounds` to an FCW. I don't want to tangle that up into the fix that was originally intended in rust-lang#136458, so I'm doing a "fix-forward" in this PR and deferring thinking about this for the future.
