Dylan DPC ac1d26bcd3 Rollup merge of #80920 - rylev:check_attr-refactor, r=davidtwco ... Visit more targets when validating attributes This begins to address #80048, allowing for additional validation of attributes. There are more refactorings that can be done, though I think they should be tackled in additional PRs: * ICE when a builtin attribute is encountered that is not checked * Move some of the attr checking done `ast_validation` into `rustc_passes` * note that this requires a bit of additional refactoring, especially of extern items which currently parse attributes (and thus are a part of the AST) but do not possess attributes in their HIR representation. * Rename `Target` to `AttributeTarget` * Refactor attribute validation completely to go through `Visitor::visit_attribute`. * This would require at a minimum passing `Target` into this method which might be too big of a refactoring to be worth it. * It's also likely not possible to do all the validation this way as some validation requires knowing what other attributes a target has. r? `@davidtwco`		2021-02-14 16:54:42 +01:00
