Changing some attributes to only_local.

Modified according to rust-lang/compiler-team#505. By running test cases, I found that modifying the attribute's only_local tag sometimes causes some unintuitive error reports, so I tend to split it into multiple PRs and edit a small number of attributes each time to prevent too many changes at once. Prevent possible subsequent difficulties in locating problems.
