…r=compiler-errors Avoid some `Symbol` to `String` conversions This patch removes some Symbol to String conversions.
Resolve function lifetime elision on the AST ~Based on rust-lang/rust#97720 Lifetime elision for functions is purely syntactic in nature, so can be resolved on the AST. This PR replicates the elision logic and diagnostics on the AST, and replaces HIR-based resolution by a `delay_span_bug`. This refactor allows for more consistent diagnostics, which don't have to guess the original code from HIR. r? `@petrochenkov`
Some command-line options accessible through `sess.opts` are best accessed through wrapper functions on `Session`, `TyCtxt` or otherwise, rather than through field access on the option struct in the `Session`. Adds a new lint which triggers on those options that should be accessed through a wrapper function so that this is prohibited. Options are annotated with a new attribute `rustc_lint_opt_deny_field_access` which can specify the error message (i.e. "use this other function instead") to be emitted. A simpler alternative would be to simply rename the options in the option type so that it is clear they should not be used, however this doesn't prevent uses, just discourages them. Another alternative would be to make the option fields private, and adding accessor functions on the option types, however the wrapper functions sometimes rely on additional state from `Session` or `TyCtxt` which wouldn't be available in an function on the option type, so the accessor would simply make the field available and its use would be discouraged too.
