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.

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.

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

Remove in_macro from clippy_utils
changelog: none
Previously done in #7897 but reverted in #8170. I'd like to keep `in_macro` out of utils because if a span is from expansion in any way (desugaring or macro), we should not proceed without understanding the nature of the expansion IMO.

New macro utils
changelog: none
Sorry, this is a big one. A lot of interrelated changes and I wanted to put the new utils to use to make sure they are somewhat battle-tested. We may want to divide some of the lint-specific refactoring commits into batches for smaller reviewing tasks. I could also split into more PRs.
Introduces a bunch of new utils at `clippy_utils::macros::...`. Please read through the docs and give any feedback! I'm happy to introduce `MacroCall` and various functions to retrieve an instance. It feels like the missing puzzle piece. I'm also introducing `ExpnId` from rustc as "useful for Clippy too". `@rust-lang/clippy`
Fixes#7843 by not parsing every node of macro implementations, at least the major offenders.
I probably want to get rid of `is_expn_of` at some point.
