`README`: document that Clippy may change codegen
Currently, Clippy does not guarantee the same codegen will be produced.
Therefore, it should not be used as an universal replacement for `rustc`.
See https://github.com/rust-lang/rust-clippy/issues/8035.

fixes#8035
changelog: document that Clippy may change codegen
Fix `deref_addrof`
fixes#8247
This would supersede #8259
changelog: Don't lint `deref_addrof` when the dereference and the borrow occur in different contexts
Improve documentation for `borrowed-box` lint
fixes#8161
Updates documentation to elaborate more on how removing Box from a function parameter can generalize the function.
changelog: none
The field is also renamed from `ident` to `name. In most cases,
we don't actually need the `Span`. A new `ident` method is added
to `VariantDef` and `FieldDef`, which constructs the full `Ident`
using `tcx.def_ident_span()`. This method is used in the cases
where we actually need an `Ident`.
This makes incremental compilation properly track changes
to the `Span`, without all of the invalidations caused by storing
a `Span` directly via an `Ident`.
Downgrade mutex_atomic to nursery
See #1516 and #4295.
There are suggestions about removing this lint from the default warned lints in both issues.
Also, [`mutex_integer`](https://rust-lang.github.io/rust-clippy/master/index.html#mutex_integer) lint that has the same problems as this lint is in `nursery` group.
changelog: Moved [`mutex_atomic`] to `nursery`
new lint: `single_char_lifetime_names`
This pull request adds a lint against single character lifetime names, as they might not divulge enough information about the purpose of the lifetime. This can make code harder to understand. I placed this in `restriction` rather than `pedantic` (as suggested in #8233) since most of the Rust ecosystem already uses single character lifetime names (to my knowledge, at least) and since single character lifetime names aren't incorrect. I'd be happy to change this upon request, however. Fixes#8233.
- [x] Followed lint naming conventions
- [x] Added passing UI tests (including committed `.stderr` file)
- [x] `cargo test` passes locally
- [x] Executed `cargo dev update_lints`
- [x] Added lint documentation
- [x] Run `cargo dev fmt`

Set binary-dep-depinfo in .cargo/config.toml
Fixes#8248
According to https://doc.rust-lang.org/cargo/reference/unstable this
seems to be the right place to set it, and it does fix the build for me.
I haven't removed the other `rustflags` because perhaps it's needed on
different cargo/rust versions?

Change `unnecessary_to_owned` `into_iter` suggestions to `MaybeIncorrect`
I am having a hard time finding a good solution for #8148, so I am wondering if is enough to just change the suggestion's applicability to `MaybeIncorrect`?
I apologize, as I realize this is a bit of a cop out.
changelog: none
Region info is completely unnecessary for upvar capture kind computation
and is only needed to create the final upvar tuple ty. Doing so makes
creation of UpvarCapture very cheap and expose further cleanup opportunity.
Allow running lintcheck with a renamed rust-clippy dir
I have Clippy checked out in `rust/clippy` rather than `rust/rust-clippy`, this allows lintcheck to still run in that case
