Explain flags missing in cargo check in --help
This commit closes#7389. As stated in the issue, `cargo clippy --help`
provides explanation for some flags and states that the rest are same
as in `cargo check --help`, even though some clippy specific flags
exist.
This commit extends the `cargo clippy --help` with two additional flags,
- `cargo clippy --fix`
- `cargo clippy --no-deps`
If there are more flags which are not present in `cargo check --help`
please bring these to my attention, I will include these aswell.
For now, I noticed only the two flags mentioned above.
changelog: `cargo clippy --help` now explains additional flags missing in `cargo check --help`.
Fix docs of disallowed_type
Add ability to name primitive types without import path
Move primitive resolution to clippy_utils path_to_res fn
Refactor Res matching, fix naming and docs from review
Use tcx.def_path_str when emitting the lint
As proposed in the pull request thread, there is some inconsistency in
handling the `--no-deps` flag which requires `--` before it, and
`--fix` flag which does not.
In this commit the `--no-deps` flag does not need the `--` anymore.
However, it can still be used that way: `cargo clipyy -- --no-deps`.
Use diagnostic items where possible
Clippy still uses a bunch of paths in places that could easily use already defined diagnostic items. This PR updates all references to such paths and also removes a bunch of them that are no longer needed after this cleanup.
Some paths are also used to construct new paths and can therefore not be removed that easily. I've added a doc comment to those instances that recommends the use of the diagnostic item where possible.
And that's it, cleaning crew signing off 🧹🗑️

Improve conflicting rlibs error again

`--no-deps` filled in with a little more information. Explain that
`--fix` implies `--no-deps`.
Explain that `--no-deps` is used with `cargo clippy --`, including
one example.
Prefer a code snipped over formatting the self type (`new_without_default`)
Fixes: rust-lang/rust-clippy#7220
changelog: [`new_without_default`]: The `Default` impl block type doesn't use the full type path qualification
Have a nice day to everyone reading this 🙃
Some `clippy::author` improvements
changelog: none
* Use `Debug` instead of re-implementing it for some things
* Fix block trailing expression handing
* Don't double print on stmt/expr with `#[clippy::author]` attribute

Store all HIR owners in the same container
This replaces the previous storage in a BTreeMap for each of Item/ImplItem/TraitItem/ForeignItem.
This should allow for a more compact storage.
Based on https://github.com/rust-lang/rust/pull/83114
Documented constant expression evaluation for `repeat_once`
Documents the fact that the `repeat_once` lint evaluates constant expressions

(I don't think it's worth a change log entry, as nothing has really changed)
r? `@giraffate` as you've implemented the lint and were part of the discussion in the issue 🙃
similar_names: No longer suggest inserting or appending an underscore
changelog: [`similar_names`] lint no longer suggests to insert or add an underscore to "fix" too similar names
New lint: [`self_named_constructor`]
Adds the `self_named_constructor` lint for detecting when an implemented method has the same name as the type it is implemented for.
changelog: [`self_named_constructor`]
closes: #7142
Remove refs from Pat slices
Changes `PatKind::Or(&'hir [&'hir Pat<'hir>])` to `PatKind::Or(&'hir [Pat<'hir>])` and others. This is more consistent with `ExprKind`, saves a little memory, and is a little easier to use.
Add instructions to run from source
changelog: none
We often get messages on Zulip asking how to install and run Clippy from source. This adds instructions to the readme. I also added a note explaining that `cargo install --path . --force` is bad, which I just decided after some investigating. I use macOS. It would be nice to get some tests on other platforms to see if this is correct.
