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.
FIx FP in `missing_safety_doc` lint
Fix FP where lint souldn't fire if any parent has `#[doc(hidden)]` attribute
fixes: #7347
changelog: [`missing_safety_doc`] Fix FP if any parent has `#[doc(hidden)]` attribute
The bug was dues to the constant bytes being compared instead of their
values. This meant that negative values were being treated as larger
than some positive values.
Fixes#7829
