Introduce `Symbol::with_interner`.

It lets you get the contents of multiple symbols with a single TLS lookup and interner lock, instead of one per symbol.

Rollup merge of #143631 - hkBst:update-escaper-2, r=compiler-errors

2025-07-17T08:41:45+00:00

update to literal-escaper-0.0.5 Quoting from the changelog, this version brings: - Use `NonZero` in `unescape_c_str` and `check_raw_c_str` to statically exclude nuls - Add `#[inline]` to small functions for improved performance

Improve path segment joining.

2025-07-16T22:37:19+00:00

There are many places that join path segments with `::` to produce a string. A lot of these use `join("::")`. Many in rustdoc use `join_with_double_colon`, and a few use `.joined("..")`. One in Clippy uses `itertools::join`. A couple of them look for `kw::PathRoot` in the first segment, which can be important. This commit introduces `rustc_ast::join_path_{syms,ident}` to do the joining for everyone. `rustc_ast` is as good a location for these as any, being the earliest-running of the several crates with a `Path` type. Two functions are needed because `Ident` printing is more complex than simple `Symbol` printing. The commit also removes `join_with_double_colon`, and `estimate_item_path_byte_length` with it. There are still a handful of places that join strings with "::" that are unchanged. They are not that important: some of them are in tests, and some of them first split a path around "::" and then rejoin with "::". This fixes one test case where `{{root}}` shows up in an error message.
