`CheckAttrVisitor::check_doc_keyword` checks `#[doc(keyword = "..")]` attributes to ensure they are on an empty module, and that the value is a non-empty identifier. The `rustc::existing_doc_keyword` lint checks these attributes to ensure that the value is the name of a keyword. It's silly to have two different checking mechanisms for these attributes. This commit does the following. - Changes `check_doc_keyword` to check that the value is the name of a keyword (avoiding the need for the identifier check, which removes a dependency on `rustc_lexer`). - Removes the lint. - Updates tests accordingly. There is one hack: the `SelfTy` FIXME case used to used to be handled by disabling the lint, but now is handled with a special case in `is_doc_keyword`. That hack will go away if/when the FIXME is fixed. Co-Authored-By: Guillaume Gomez <guillaume1.gomez@gmail.com>
