df65291edd Auto merge of #7856 - Manishearth:impl-safety, r=xFrednet 
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.

changelog: handle 'implementation safety' headers in `missing_safety_doc`

300b821d51 Auto merge of #7838 - nhamovitz:trailing_zs_arr_wo_repr, r=Manishearth 
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.
