Fixes rust-lang#66667 Previously, we called `tcx.typeck_tables_of` when determining whether or not to emit a suggestion for a type error. However, we might already be type-checking the `DefId` we pass to `typeck_tables_of` (it could be anywhere in the query stack). Fortunately, we only need the function signature, not the entire `TypeckTables`. By using `tcx.fn_sig`, we avoid the possibility of cycle errors while retaining the ability to emit a suggestion.
…anup, r=eddyb Remove framework in `dataflow/mod.rs` in favor of "generic" one This is the culmination of the work described in rust-lang/compiler-team#202. All dataflow analyses (including the one in `clippy`) have been ported to use the framework in `dataflow/generic`, which can efficiently handle both gen/kill and generic problems. This PR moves the framework in `dataflow/generic` to `dataflow/framework`, and removes the gen/kill framework in `dataflow/mod.rs`. More comprehensive documentation for the new framework is tracked in rust-lang/rustc-dev-guide#564. `clippy` will need to change the path it uses to import the dataflow analysis traits.

Allow obtaining &mut OsStr
```rust
impl DerefMut for OsString {...} // type Target = OsStr
impl IndexMut<RangeFull> for OsString {...} // type Output = OsStr
```

This change is pulled out of rust-lang#69937 per @dtolnay
This implements `DerefMut for OsString` to allow obtaining a `&mut OsStr`. This also implements `IndexMut for OsString`, which is used by `DerefMut`. This pattern is the same as is used by `Deref`.
This is necessary to for methods like `make_ascii_lowercase` which need to mutate the underlying value.
Decouple `rustc_hir::print` into `rustc_hir_pretty` High level summary: - The HIR pretty printer, `rustc_hir::print` is moved into a new crate `rustc_hir_pretty`. - `rustc_ast_pretty` and `rustc_errors` are dropped as `rustc_hir` dependencies. - The dependence on HIR pretty is generally reduced, leaving `rustc_save_analysis`, `rustdoc`, `rustc_metadata`, and `rustc_driver` as the remaining clients. The main goal here is to reduce `rustc_hir`'s dependencies and its size such that it can start and finish earlier, thereby working towards rust-lang#65031. r? @Zoxc
