Less authoritative stable_sort_primitive message
fixes#8241
Hey all - first contribution here so I'm deciding to start with something small.
Updated the linked message to be less authoritative as well as moved the lint grouping from `perf` to `pedantic` as suggested by `@camsteffen` under the issue.
changelog: [`stable_sort_primitive`]: emit less authoritative message and move to `pedantic`
Fix needless_match false positive for if-let when the else block doesn't match to given expr

Thank you for making Clippy better!
We're collecting our changelog from pull request descriptions.
If your PR only includes internal changes, you can just write
`changelog: none`. Otherwise, please write a short comment
explaining your change. Also, it's helpful for us that
the lint name is put into brackets `[]` and backticks `` ` ` ``,
e.g. ``[`lint_name`]``.
If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.
If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.
- \[ ] Followed [lint naming conventions][lint_naming]
- \[ ] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[ ] Added lint documentation
- \[x] Run `cargo dev fmt`

Report undeclared lifetimes during late resolution.
First step in https://github.com/rust-lang/rust/pull/91557
We reuse the rib design of the current resolution framework. Specific `LifetimeRib` and `LifetimeRibKind` types are introduced. The most important variant is `LifetimeRibKind::Generics`, which happens each time we encounter something which may introduce generic lifetime parameters. It can be an item or a `for<...>` binder. The `LifetimeBinderKind` specifies how this rib behaves with respect to in-band lifetimes.

Refactor HIR item-like traversal (part 1)
Issue #95004
- Create hir_crate_items query which traverses tcx.hir_crate(()).owners to return a hir::ModuleItems
- use tcx.hir_crate_items in tcx.hir().items() to return an iterator of hir::ItemId
- use tcx.hir_crate_items to introduce a tcx.hir().par_items(impl Fn(hir::ItemId)) to traverse all items in parallel;

New lint `format_add_strings`
Closes#6261
changelog: Added [`format_add_string`]: recommend using `write!` instead of appending the result of `format!`
Add `usize` cast to `clippy::manual_bits` suggestion
A fix for the suggestion from https://github.com/rust-lang/rust-clippy/pull/8213
changelog: [`manual_bits`]: The suggestion now includes a cast for proper type conversion
This adds test to make sure correct behavior of lint
- The first test's option variable is not a temporary variable
- The second test does not make usage of `take()`
- The third test makes usage of `take()` and uses a temporary variable
This lint checks if Option::take() is used on a temporary value (a value
that is not of type &mut Option and that is not a Place expression) to
suggest omitting take()
Check for loops/closures in `local_used_after_expr`
Follow up to #8646, catches when a local is used multiple times because it's in a loop or a closure

fix unnecessary_to_owned about msrv
This PR fixes ``[`unnecessary_owned`]``.
## What
```rust
# sample code
fn _msrv_1_35() {
#![clippy::msrv = "1.35"]
let _ = &["x"][..].to_vec().into_iter();
}
fn _msrv_1_36() {
#![clippy::msrv = "1.36"]
let _ = &["x"][..].to_vec().into_iter();
}
```
If we will check this code using clippy, ``[`unnecessary_owned`]`` will modify the code as follows.
```rust
error: unnecessary use of `to_vec`
--> $DIR/unnecessary_to_owned.rs:219:14
|
LL | let _ = &["x"][..].to_vec().into_iter();
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: use: `["x"][..].iter().copied()`
error: unnecessary use of `to_vec`
--> $DIR/unnecessary_to_owned.rs:224:14
|
LL | let _ = &["x"][..].to_vec().into_iter();
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: use: `["x"][..].iter().copied()`
```
This is incorrect. Because `Iterator::copied` was estabilished in 1.36.
## Why
This bug was caused by not separating "copied" and "clone" by reference to msrv.
89ee6aa6e3/clippy_lints/src/methods/unnecessary_to_owned.rs (L195)
So, I added a conditional branch and described the corresponding test.
Thank you in advance.

Don't lint various match lints when expanded by a proc-macro

As always for proc-macro output this is a hack-job of a fix. It would be really nice if more proc-macro authors would set spans correctly.
