TraitKind -> Trait
TyAliasKind -> TyAlias
ImplKind -> Impl
FnKind -> Fn
All `*Kind`s in AST are supposed to be enums.
Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order.
Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.
Add `cargo dev lint` to manually run clippy on a file
I found the manual run command really useful, this makes it a bit easier to type
Not sure if this belongs in the changelog or not

Replace `in_macro` usage with `from_expansion`
changelog: none
Generally replace `in_macro(span)` with `span.from_expansion()`. If we're just trying to avoid expanded code, this seems more appropriate because any kind of expanded code is prone to false positives. One place I did not touch is `macro_use.rs`. I think this lint could use a rewrite so I moved `in_macro` there, the only place it is still used.
Reference `clippy_utils` docs on nightly-rustc and some other documentation updates
The `clippy_utils` crate is now part of the nightly-rustc documentation. See [**very beautiful documentation**](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/). This PR references them in our documentation and updates some other documentation.

Update Clippy dependencies
Clippy has two outdated dependencies, where one indirect dependency has been flagged by rustsec for dropping a lifetime. See [RUSTSEC-2020-0146](https://rustsec.org/advisories/RUSTSEC-2020-0146). This PR updates these dependencies.
With previous dependency updates, it was tried to prevent duplicates in the `Cargo.lock` file of rust-lang/rust. I've tried to keep this in mind with this update.
* Dependency `semver`
* Used in `src/tools/cargo/Cargo.toml` as version `1.0.3`
* Used in `src/tools/rust-analyzer/crates/project_model/Cargo.toml` as version `1`
* Updated in Clippy from `0.11` to `1.0` (Clippy usually defines the major and minor patch version). The `Cargo.lock` file lists `1.0.3` which is one patch version behind the most recent one but prevents a duplicate with cargo's pinned version.
* Dependency `cargo_metadata`
* Used in several tools as `0.14`
* Used in `src/tools/tidy` and `src/tools/rls` as `0.12`
* Updated in Clippy from `0.12` to `0.14`
All updates to the `Cargo.lock` have been done automatically by `x.py`.
There are still some tools with these outdated dependencies. Clippy didn't require any changes, and it would be likely that the others could also be updated without any problem. Let me know if I should try to update them as well 🙃.
Keep up the good work, whoever is reading this 🦀

Use .cargo/config.toml instead of .cargo/config
`.cargo/config.toml` is the preferred form for the local configuration file. This is emphasized in _The Cargo Book_ with the following note:
> Note: Cargo also reads config files without the `.toml` extension, such as `.cargo/config`. Support for the `.toml` extension was added in version 1.39 and is the preferred form.
Moreover, this helps with toml-aware text editors as they will recognize the file extension.

Move non_ascii_literal to restriction
It feels like the more apt category, since cases where you'd want it enabled would be pretty specific

Prevent clippy::needless_lifetimes false positive in async function definition
Scan `OpaqueDef` bounds for lifetimes as well. Those `OpaqueDef` instances are generated while desugaring an `async` function definition.
This fixes#7893

Fix manual_assert and match_wild_err_arm for `#![no_std]` and Rust 2021
Rust 2015 `std::panic!` has a wrapping block while `core::panic!` and Rust 2021 `std::panic!` does not. See rust-lang/rust#88919 for details.
Note that the test won't pass until clippy changes in rust-lang/rust#88860 is synced.

Unseparated literal suffix
Closes#7658
Since `literal_suffix` style is opinionated, we should disable by default and only enforce if it's stated as so.
changelog: [`unseparated_literal_suffix`] is renamed to `literal_suffix`, adds a new configuration `literal-suffix-style` to enforce a certain style writing literal_suffix. Possible values for `literal-suffix-style`: `"separated"`, `"unseparated"`
