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

2024-12-18T02:38:53+00:00

`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.

Rename all `ParseSess` variables/fields/lifetimes as `psess`.

2024-03-04T21:11:45+00:00

Existing names for values of this type are `sess`, `parse_sess`, `parse_session`, and `ps`. `sess` is particularly annoying because that's also used for `Session` values, which are often co-located, and it can be difficult to know which type a value named `sess` refers to. (That annoyance is the main motivation for this change.) `psess` is nice and short, which is good for a name used this much. The commit also renames some `parse_sess_created` values as `psess_created`.

Remove `ExtCtxt` methods that duplicate `DiagCtxt` methods.

Fix `clippy::needless_borrow` in the compiler

`x clippy compiler -Aclippy::all -Wclippy::needless_borrow --fix`. Then I had to remove a few unnecessary parens and muts that were exposed now.
