Allow raw lint descriptions
update_lints now understands raw strings in declare_clippy_lint descriptions.
Supersedes #8655
cc `@Alexendoo` thanks for addressing this so quickly. I build a little bit simpler version of your patch. I don't think it really matters what `Literal` we're trying to tokenize, since we assume later, that it is some sort of `str`.

update unnecessary_join documentation
changelog: none
Updates the description of `unnecessary_join` in accordance with https://github.com/rust-lang/rust-clippy/pull/8579#issuecomment-1089969859. I've also added a line regarding differences in assembly output, please let me know if it should also make it in.
Auto merge of #8612 - SabrinaJewson:suggest-from-utf8-unchecked-in-const, r=flip1995
Suggest from_utf8_unchecked in const contexts
Unfortunately I couldn't figure out how to check whether a given expression is in an `unsafe` context or not, so I just unconditionally emit the wrapping `unsafe {}` block in the suggestion. If there is an easy way to get it to work better then I would love to hear it.
changelog: Suggest `from_utf8_unchecked` instead of `from_utf8` in const contexts for ``[`transmute_bytes_to_str`]``

Auto merge of #8620 - Alexendoo:test-fmt-first, r=flip1995
Run fmt test before compile-test/dogfood
I seem to always forget to run `cargo dev fmt` before doing a test. This lets it fail fast rather than going through the much longer compile-test/dogfood tests first
Auto merge of #8607 - Alexendoo:cargo-dev-lint-dir, r=flip1995,giraffate
Allow running `cargo dev lint` on a package directory
Allows you run the local clippy in a specified directory, e.g. allowing
```sh
# Lint a ui-cargo test
cargo dev lint tests/ui-cargo/wildcard_dependencies/fail
# Lint some other project
cargo dev lint ~/my-project
```
The `target` directory is set to a tempdir which isn't ideal for medium/large projects as it would be compiled from scratch. This is to avoid cached clippy messages where you `cargo dev lint dir`, change something in clippy, and run `cargo dev lint dir` again
changelog: Dev: `cargo dev lint` can now be run on a package directory

errors: implement fallback diagnostic translation
This commit updates the signatures of all diagnostic functions to accept
types that can be converted into a `DiagnosticMessage`. This enables
existing diagnostic calls to continue to work as before and Fluent
identifiers to be provided. The `SessionDiagnostic` derive just
generates normal diagnostic calls, so these APIs had to be modified to
accept Fluent identifiers.
In addition, loading of the "fallback" Fluent bundle, which contains the
built-in English messages, has been implemented.
Each diagnostic now has "arguments" which correspond to variables in the
Fluent messages (necessary to render a Fluent message) but no API for
adding arguments has been added yet. Therefore, diagnostics (that do not
require interpolation) can be converted to use Fluent identifiers and
will be output as before.

span: move `MultiSpan`
`MultiSpan` contains labels, which are more complicated with the
introduction of diagnostic translation and will use types from
`rustc_errors` - however, `rustc_errors` depends on `rustc_span` so
`rustc_span` cannot use types like `DiagnosticMessage` without
dependency cycles. Introduce a new `rustc_error_messages` crate that can
contain `DiagnosticMessage` and `MultiSpan`.
Auto merge of #8632 - Jarcho:cast_ptr_alignment, r=llogiq
Don't lint `cast_ptr_alignment` when used for unaligned reads and writes
fixes #2881
Ideally this would trace the usage of the value rather than only looking at the parent expression, but that would require dataflow analysis. e.g.
```rust
let x = ptr as *const u16;
c.read_unaligned(x);
```
Arch specific intrinsic functions need to be checked for ones which could take an unaligned pointer. This can be another PR.

We're collecting our changelog from pull request descriptions.
If your PR only includes internal changes, you can just write
`changelog: none`. Otherwise, please write a short comment
explaining your change. Also, it's helpful for us that
the lint name is put into brackets `[]` and backticks `` ` ` ``,
e.g. ``[`lint_name`]``.
If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.
If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.
Auto merge of #8605 - Jarcho:remove-deps, r=xFrednet
Remove deps
This remove both `regex` and `cargo_metadata` as dependencies making `clippy_dev` compile ~3x faster (~46s -> ~16s locally). `cargo_metadata` was used to extract the `version` field from `Cargo.toml`, which is done trivially without that. `regex` was used to parse `define_clippy_lint` in `update_lints` which is now done using `rustc_lexer`. This isn't any simpler, but it compiles ~15s faster and runs ~3x faster (~2.1s -> ~0.7s locally).
The next biggest offenders to compile times are `clap` and `winapi` on windows. `clap` could be removed, but re-implementing enough is probably more work than it's worth. `winapi` is used by `opener` and `walkdir` so it's stuck there.
Auto merge of #8611 - Alexendoo:module-files-relative-paths, r=llogiq
Handle relative paths in module_files lints
The problem being that when clippy is run in the project's directory `lp` would be a relative path, this wasn't caught by the tests as there `lp` is an absolute path. Being a relative path it did not start with `trim_src_path` and so was ignored
Also allowed the removal of some `.to_os_string`/`.to_owned`s

Add `crate_in_macro_def` lint
This PR adds a lint to check for `crate` as opposed to `$crate` used in a macro definition.
I think this can close #4798. That issue focused on the case where the macro author "imports something into said macro."
But I think use of `crate` is likely to be a bug whether it appears in a `use` statement or not. There could be some use case I am failing to see, though. (cc: `@nilscript` `@flip1995)`

Do not fire `panic` in a constant environment

Since https://github.com/rust-lang/rust-clippy/issues/8348 I thought that such modification would require a lot of work but thanks to https://github.com/rust-lang/rust-clippy/pull/8588 I now know that it is not the case.
