1. Convert IfNotElse to LateLintPass and use clippy_utils::is_else_clause for checking.
2. Handle the case where the span comes from desugaring.
3. Update tests.
Ignore references to type aliases in ptr_arg
Works using the fact that the hir path will point to a TyAlias, rather than being resolved to the underlying type
Fixes#7699
changelog: [`ptr_arg`] No longer lints references to type aliases
Add unit-hash lint
changelog: [`unit_hash`] Add lint for hashing unit values
This will lint for situations where the end user is attempting to hash a unit value (`()`), as the implementation in `std` simply [does nothing][impl]. Closes#7159 .
Example:
```rust
().hash(&mut state);
// Should (probably) be replaced with:
0_u8.hash(&mut state);
```
[impl]: a5f164faad/library/core/src/hash/mod.rs (L656)
Register the generated lints from `cargo dev new_lint`
How to register a lint was something that took me a couple reads to figure out, this will hopefully make that easier. It appends the created lint to the end of the list when running `cargo dev new_lint`

Fix `question_mark` FP on custom error type
Closes#7859#7840 aims to ignore `question_mark` when the return type is custom, which is [covered here](df65291edd/tests/ui/question_mark.rs (L144-L149)). But this fails when there is a call in conditional predicate
changelog: [`question_mark`] Fix false positive when there is call in conditional predicate
Clean up tests/ui/rename.rs
Part one of #7057, cleaning up `tests/ui/rename.rs`. `tests/ui/deprecated.rs` will be updated in a subsequent PR.

new lint: string-slice
This is a restriction lint to highlight code that should have tests containing non-ascii characters. See #6623.
changelog: new lint: [`string-slice`]
Fix `match_str_case_mismatch` on uncased chars
False positives would result because `char::is_lowercase` and friends will return `false` for non-alphabetic chars and alphabetic chars lacking case (such as CJK scripts). Care also has to be taken for handling titlecase characters (`Dz`) and lowercased chars with no uppercase equivalent (`ʁ`).
For example, when verifying lowercase:
* Check `!any(char::is_ascii_uppercase)` instead of `all(char::is_ascii_lowercase)` for ASCII.
* Check that `all(|c| c.to_lowercase() == c)` instead of `all(char::is_lowercase)` for non-ASCII
Fixes#7863.

Update `str` utils to prevent ICEs and FNs
This PR reworks some string handling for lints regarding enum naming. I hope the refactoring will prevent future ICEs and help with new bug free implementations.
It might be better to review this PR by going through the commits, as `clippy_utils::camel_case` was renamed to `clippy_utils::str_utils` and then changed further. GH sadly doesn't really make the changes that obvious 🙃
Not too much more to say. Have a nice day 🌞

recommend new branch or deleting branch when synching from rust

r? `@flip1995` - thanks again for your assistance in zulip earlier, figured I'd take a pass at incorporating your recommendation to delete or use a new branch into the excellent docs here
Don't mark for loop iter expression as desugared
We typically don't mark spans of lowered things as desugared. This helps Clippy rightly discern when code is (not) from expansion. This was discovered by ``@flip1995`` at https://github.com/rust-lang/rust-clippy/pull/7789#issuecomment-939289501.
