Clean up more comments near use declarations

rust-lang#125443 will reformat all use declarations in the repository. There are a few edge cases involving comments on use declarations that require care. This PR fixes them up so rust-lang#125443 can go ahead with a simple `x fmt --all`. A follow-up to rust-lang#126717.
