Auto merge of #9136 - smoelius:enhance-needless-borrow, r=Jarcho
Enhance `needless_borrow` to consider trait implementations
The proposed enhancement causes `needless_borrow` to suggest removing `&` from `&e` when `&e` is an argument position requiring trait implementations, and `e` implements the required traits. Example:
```
error: the borrowed expression implements the required traits
--> $DIR/needless_borrow.rs:131:51
|
LL | let _ = std::process::Command::new("ls").args(&["-a", "-l"]).status().unwrap();
| ^^^^^^^^^^^^^ help: change this to: `["-a", "-l"]`
```

changelog: [`case_sensitive_file_extension_comparisons `]: updated suggestion in the example to use `map_or`

Auto merge of #96745 - ehuss:even-more-attribute-validation, r=cjgillot
Visit attributes in more places.
This adds 3 loosely related changes (I can split PRs if desired):
- Attribute checking on pattern struct fields.
- Attribute checking on struct expression fields.
- Lint level visiting on pattern struct fields, struct expression fields, and generic parameters.
There are still some lints which ignore lint levels in various positions. This is a consequence of how the lints themselves are implemented. For example, lint levels on associated consts don't work with `unused_braces`.

I'm unsure especially about the `Sugg`, as it covers the entire `BinOp`, instead of just covering one of the sides and the operator (see the multi-line example). I was unsure if pinpointing the suggestion wouldn't be brittle...

This is a more general way of checking if an expression comes from a macro and could be trivially applied to other lints. Ideally this would be fixed in rustc's proc-macro api, but I don't see that happening any time soon.
