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 🌞

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.
missing_safety_doc: Handle 'implementation safety' headers as well
We hit some FPs on this in `yoke`, it's somewhat normal to mark trait impl safety with "implementation safety". We could also broaden the check for headers which contain the word "safety" somehow, or split out impl safety stuff to only apply to traits.

Warn on structs with a trailing zero-sized array but no `repr` attribute
Closes#2868
changelog: Implement ``[`trailing_empty_array`]``, which warns if a struct is defined where the last field is a zero-sized array but there are no `repr` attributes. Zero-sized arrays aren't very useful in Rust itself, so such a struct is likely being created to pass to C code or in some other situation where control over memory layout matters. Either way, a `repr` attribute is needed.
