`identity_op`: add parenthesis to suggestions where required
changelog: [`identity_op`]: add parenthesis to suggestions where required
Follow up to #8730, wraps the cases we can't lint as-is in parenthesis rather than ignoring them
Catches a couple new FPs with mixed operator precedences and `as` casts
```rust
// such as
0 + { a } * 2;
0 + a as usize;
```
The suggestions are now applied using `span_lint_and_sugg` rather than appearing in just the message and have a `run-rustfix` test
Fix imports for "Checking if a type defines a specific method"
The import of `clippy_utils::is_type_diagnostic_item` would cause this error:
```
error[E0432]: unresolved import `clippy_utils::is_type_diagnostic_item

Rustup
`@rust-lang/clippy,` `@Jarcho,` `@dswij,` `@Alexendoo.` Could someone review this? It should be pretty straight forward since it's just a sync. I think it's also fine if either one of `@Jarcho,` `@dswij,` `@Alexendoo` approves this, as these are usually not reviewed. I just want to make sure that I didn't break something obvious 🙃
It should be enough to look at the merge commit 🙃

Mini changelog update for Rust 1.61.0
I'll do the full release and sync tomorrow, as I sadly don't have the time today. This is a quick update to ensure that Rust's changelog will link to the correct section in our changelog. The change is according to [our docs](8751e47bae/book/src/development/infrastructure/release.md (update-changelogmd))

[dbg_macro] tolerates use of `dbg!` in items which have `#[cfg(test)]` attribute

Improve "unknown field" error messages
Fixes#8806

You can test this by (say) adding `foobar = 42` to Clippy's root `clippy.toml` file, and running `cargo run --bin cargo-clippy`.
Note that, to get the terminal width, this PR adds `termize` as a dependency to `cargo-clippy`. However, `termize` is also [how `rustc_errors` gets the terminal width](481db40311/compiler/rustc_errors/src/emitter.rs (L1607)). So, hopefully, this is not a dealbreaker.

changelog: Enhancements: the "unknown field" error messages for config files now wraps the field names.
Change `Successors` to `impl Iterator<Item = BasicBlock>`
This PR fixes the FIXME in `compiler\rustc_middle\src\mir\mod.rs`.
This can omit several `&`, `*` or `cloned` operations on Successros' generated elements
Add a query for checking whether a function is an intrinsic.
work towards #93145
This will reduce churn when we add more ways to declare intrinsics

add suggestions to rc_clone_in_vec_init
A followup to https://github.com/rust-lang/rust-clippy/pull/8769
I also switch the order of the 2 suggestions, since the loop initialization one is probably the common case.
`@xFrednet` I'm not letting you guys rest for a minute 😅

`undocumented_unsafe_blocks` does not trigger on unsafe trait impls
Closes#8505
changelog: This lint checks unsafe impls NOT from macro expansions and checks ones in macro declarations.
~~`unsafe impl`s from macro invocations don't trigger the lint for now.~~
~~This lint checks unsafe impls from/not from macro expansions~~
Don't lint `vec_init_then_push` when further extended
fixes#7071
This will still lint when a larger number of pushes are done (four currently). The exact number could be debated, but this is more readable then a sequence of pushes so it shouldn't be too large.
changelog: Don't lint `vec_init_then_push` when further extended.
changelog: Remove `mut` binding from `vec_init_then_push` when possible.
Rename `eval_order_dependence` to `mixed_read_write_expression`, move to nursery
As per the [reference](https://doc.rust-lang.org/1.51.0/reference/expressions.html#evaluation-order-of-operands) evaluation order is now defined.
I'm pretty sure rust always compiled with this evaluation order anyways so there's no reason the put an msrv limit on the lint.
