…lacrum Move more of `rustc::lint` into `rustc_lint` Based on rust-lang#67806. Here we try to consolidate more of the linting infra into `rustc::lint`. Some high-level notes: - We now store an `Lrc<dyn Any + Send + Sync>` as opposed to `Lrc<LintStore>` in the `GlobalCtxt`. This enables us to avoid referring to the type, breaking a cyclic dependency, and so we can move things from `rustc::lint` to `rustc_lint`. - `in_derive_expansion` is, and needs to, be moved as a method on `Span`. - We reduce the number of ways on `tcx` to emit a lint so that the developer UX is more streamlined. - `LintLevelsBuilder` is moved to `rustc_lint::levels`, leaving behind `LintLevelMap/Set` in a purified form due to current constraints (hopefully fixable in the future after rust-lang#68133). - `struct_lint_level` is moved to `rustc::lint` due to current dependency constraints. - `rustc::context` is moved to `rustc_lint::context`. - The visitors in `rustc::lint` are moved to `rustc_lint::passes`.

Slimmer syntax High-level summary of changes: - The `syntax::node_count` pass is moved into `rustc_ast_passes`. This works towards improving #65031 by making compiling `syntax` go faster. - The `syntax::{GLOBALS, with_globals, ..}` business is consolidated into `syntax::attr` for cleaner code and future possible improvements. - The pretty printer loses its dependency on `ParseSess`, opting to use `SourceMap` & friends directly instead. - Some drive by cleanup of `syntax::attr::HasAttr` happens. - Builtin attribute logic (`syntax::attr::builtin`) + `syntax::attr::allow_internal_unstable` is moved into a new `rustc_attr` crate. More logic from `syntax::attr` should be moved into that crate over time. This also means that `syntax` loses all mentions of `ParseSess`, which enables the next point. - The pretty printer `syntax::print` is moved into a new crate `rustc_ast_pretty`. - `rustc_session::node_id` is moved back as `syntax::node_id`. As a result, `syntax` gets to drop dependencies on `rustc_session` (and implicitly `rustc_target`), `rustc_error_codes`, and `rustc_errors`. Moreover `rustc_hir` gets to drop its dependency on `rustc_session` as well. At this point, these crates are mostly "pure data crates", which is approaching a desirable end state. - We should consider renaming `syntax` to `rustc_ast` now.
