Add as_ptr_cast_mut lint 
This lint detects calls to a `&self`-taking `as_ptr` method, where
the result is then immediately cast to a `*mut T`. Code like this
is probably invalid, as that pointer will not have write permissions,
and `*mut T` is usually used to write through.

avoid doc-link-with-quotes in code blocks

This fixes #8961 by moving the lint into the docs code, thus being able to re-use the pulldown-cmark parser and simplifying the code.

rustc_tool_utils: bump version in anticipation of a new release

cc https://github.com/rust-lang/rust-clippy/issues/9553

After this is merged, I will publish the 0.2.1 version to crates.io, and make another PR that switches clippy to use the dependency from crates.io.
The source can still be kept in the clippy repo though imo.

This will allow miri and clippy to "share" the crate in the rustc repo once they both depend on it.

reopen of #9561

changelog: release `rustc_tools_util` on `Crates.io`.

9e8f53d09a Auto merge of #101986 - WaffleLapkin:move_lint_note_to_the_bottom, r=estebank 
Move lint level source explanation to the bottom

So, uhhhhh

r? `@estebank`

## User-facing change

"note: `#[warn(...)]` on by default" and such are moved to the bottom of the diagnostic:
```diff
-   = note: `#[warn(unsupported_calling_conventions)]` on by default
   = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
   = note: for more information, see issue #87678 <https://github.com/rust-lang/rust/issues/87678>
+   = note: `#[warn(unsupported_calling_conventions)]` on by default
```

Why warning is enabled is the least important thing, so it shouldn't be the first note the user reads, IMO.

## Developer-facing change

`struct_span_lint` and similar methods have a different signature.

Before: `..., impl for<'a> FnOnce(LintDiagnosticBuilder<'a, ()>)`
After: `..., impl Into<DiagnosticMessage>, impl for<'a, 'b> FnOnce(&'b mut DiagnosticBuilder<'a, ()>) -> &'b mut DiagnosticBuilder<'a, ()>`

The reason for this is that `struct_span_lint` needs to edit the diagnostic _after_ `decorate` closure is called. This also makes lint code a little bit nicer in my opinion.

Another option is to use `impl for<'a> FnOnce(LintDiagnosticBuilder<'a, ()>) -> DiagnosticBuilder<'a, ()>` altough I don't _really_ see reasons to do `let lint = lint.build(message)` everywhere.

## Subtle problem

By moving the message outside of the closure (that may not be called if the lint is disabled) `format!(...)` is executed earlier, possibly formatting `Ty` which may call a query that trims paths that crashes the compiler if there were no warnings...

I don't think it's that big of a deal, considering that we move from `format!(...)` to `fluent` (which is lazy by-default) anyway, however this required adding a workaround which is unfortunate.

## P.S.

I'm sorry, I do not how to make this PR smaller/easier to review. Changes to the lint API affect SO MUCH 😢

Add `cargo lintcheck --recursive` to check dependencies of crates

r? `@matthiaskrgr`

This just adds the mode without changing how a regular run works

Takes a fair bit longer to run than a `-j4` or regular run

```

8b59fe4981 Shrink hir::def::Res. 
`Res::SelfTy` currently has two `Option`s. When the second one is `Some`
the first one is never consulted. So we can split it into two variants,
`Res::SelfTyParam` and `Res::SelfTyAlias`, reducing the size of `Res`
from 24 bytes to 12. This then shrinks `hir::Path` and
`hir::PathSegment`, which are the HIR types that take up the most space.

Left a couple debug derived impls on purpose I needed to debug as I don't think it's noise

add `box-default` lint

This adds a `box-default` lint to suggest using `Box::default()` instead of `Box::new(Default::default())`, which offers less moving parts and potentially better performance according to [the perf book](https://nnethercote.github.io/perf-book/standard-library-types.html#box).

fix https://github.com/rust-lang/rust-clippy/issues/7358,
fix #9192,
fix https://github.com/rust-lang/rust-clippy/issues/9503

changelog: [`needless_return`] Recursively remove unneeded semicolons

For now the suggestion about removing the semicolons are hidden because they would be very noisy and should be obvious if the user wants to apply the lint manually instead of using `--fix`. This could be an issue for beginner, but haven't found better way to display it.

[arithmetic-side-effects] Consider references

Takes into consideration integer references like `&i32::MAX` because currently things like `let _ = &1 + 0` trigger the lint.

Don't lint `*_interior_mutable_const` on unions due to potential ICE.

fixes #9445
cc rust-lang/rust#101113

This started ICE'ing sometime last month due to stricter UB checks. I'm not sure how we could check the value of a union as MIRI doesn't seem to store which field is currently active.

changelog: Don't ICE on const unions containing a `!Freeze` type.
