Replace infallible `name_or_empty` methods with fallible `name` methods.

2025-04-16T23:50:52+00:00

I'm removing empty identifiers everywhere, because in practice they always mean "no identifier" rather than "empty identifier". (An empty identifier is impossible.) It's better to use `Option` to mean "no identifier" because you then can't forget about the "no identifier" possibility. Some specifics: - When testing an attribute for a single name, the commit uses the `has_name` method. - When testing an attribute for multiple names, the commit uses the new `has_any_name` method. - When using `match` on an attribute, the match arms now have `Some` on them. In the tests, we now avoid printing empty identifiers by not printing the identifier in the `error:` line at all, instead letting the carets point out the problem.

Re-export more `rustc_span::symbol` things from `rustc_span`.

`rustc_span::symbol` defines some things that are re-exported from `rustc_span`, such as `Symbol` and `sym`. But it doesn't re-export some closely related things such as `Ident` and `kw`. So you can do `use rustc_span::{Symbol, sym}` but you have to do `use rustc_span::symbol::{Ident, kw}`, which is inconsistent for no good reason. This commit re-exports `Ident`, `kw`, and `MacroRulesNormalizedIdent`, and changes many `rustc_span::symbol::` qualifiers in `compiler/` to `rustc_span::`. This is a 200+ net line of code reduction, mostly because many files with two `use rustc_span` items can be reduced to one.

Add `warn(unreachable_pub)` to `rustc_incremental`.

Reformat `use` declarations.

The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.
