Remove the `overlapping_marker_traits` feature See #29864 This has been replaced by `#[feature(marker_trait_attr)]` A few notes: * Due to PR #68057 not yet being in the bootstrap compiler, it's necessary to continue using `#![feature(overlapping_marker_traits)]` under `#[cfg(bootstrap)]` to work around type inference issues. * I've updated tests that used `overlapping_marker_traits` to now use `marker_trait_attr` where applicable The test `src/test/ui/overlap-marker-trait.rs` doesn't make any sense now that `overlapping_marker_traits`, so I removed it. The test `src/test/ui/traits/overlap-permitted-for-marker-traits-neg.rs` now fails, since it's no longer possible to have multiple overlapping negative impls of `Send`. I believe that this is the behavior we want (assuming that `Send` is not going to become a `#[marker]` trait, so I renamed the test to `overlap-permitted-for-marker-traits-neg` 2020-01-25 14:30:19 -06:00			error[E0119]: conflicting implementations of trait `std::marker::Send` for type `MyStruct`:
