Auto merge of #53693 - scottmcm:marker-trait-attribute, r=nikomatsakis
Support an explicit annotation for marker traits From the tracking issue for rust-lang/rfcs#1268: > It seems obvious that we should make a `#[marker]` annotation. ~ https://github.com/rust-lang/rust/issues/29864#issuecomment-368959441 This PR allows you to put `#[marker]` on a trait, at which point: - [x] The trait must not have any items ~~All of the trait's items must have defaults~~ - [x] Any impl of the trait must be empty (not override any items) - [x] But impls of the trait are allowed to overlap r? @nikomatsakis
