Make MIR basic blocks field public
This makes it possible to mutably borrow different fields of the MIR
body without resorting to methods like `basic_blocks_local_decls_mut_and_var_debug_info`.
To preserve validity of control flow graph caches in the presence of
modifications, a new struct `BasicBlocks` wraps together basic blocks
and control flow graph caches.
The `BasicBlocks` dereferences to `IndexVec<BasicBlock, BasicBlockData>`.
On the other hand a mutable access requires explicit `as_mut()` call.
Finishing touches for `#[expect]` (RFC 2383)
This PR adds documentation and some functionality to rustc's lint passes, to manually fulfill expectations. This is needed for some lints in Clippy. Hopefully, it should be one of the last things before we can move forward with stabilizing this feature.
As part of this PR, I've also updated `clippy::duplicate_mod` to showcase how this new functionality can be used and to ensure that it works correctly.

changelog: [`duplicate_mod`]: Fixed lint attribute interaction

And I guess that's it. Here have a magical unicorn 🦄
the two loops did practically the same, only the type were different (&&
vs &), so I used `copied` to convert `&&` and chained them together.
Instead of parsing the trait info manually, I use the already provided
method `get_trait_info_from_bound`.
Also, instead of using manual string writing, I used `join` by
`itertools`.

Don't know how useful of a lint this is, just saw this was a really old issue 😄.

Add details about how significant drop in match scrutinees can cause deadlocks
Adds more details about how a significant drop in a match scrutinee can cause a deadlock and include link to documentation.
changelog: Add more details to significant drop lint to explicitly show how temporaries in match scrutinees can cause deadlocks.
Fix `#[expect]` for most clippy lints
This PR fixes most `#[expect]` - lint interactions listed in rust-lang/rust#97660. [My comment in the issue](https://github.com/rust-lang/rust/issues/97660#issuecomment-1147269504) shows the current progress (Once this is merged). I plan to work on `duplicate_mod` and `multiple_inherent_impl` and leave the rest for later. I feel like stabilizing the feature is more important than fixing the last few nits, which currently also don't work with `#[allow]`.

Add lint `explicit_auto_deref` take 2
fixes: #234fixes: #8367fixes: #8380
Still things to do:
* ~~This currently only lints `&*<expr>` when it doesn't trigger `needless_borrow`.~~
* ~~This requires a borrow after a deref to trigger. So `*<expr>` changing `&&T` to `&T` won't be caught.~~
* The `deref` and `deref_mut` trait methods aren't linted.
* Neither ~~field accesses~~, nor method receivers are linted.
* ~~This probably shouldn't lint reborrowing.~~
* Full slicing to deref should probably be handled here as well. e.g. `&vec[..]` when just `&vec` would do
changelog: new lint `explicit_auto_deref`
