introduce `negative_impls` feature gate and document They used to be covered by `optin_builtin_traits` but negative impls are now applicable to all traits, not just auto traits. This also adds docs in the unstable book for the current state of auto traits. 2020-01-09 04:56:38 -06:00			`error[E0658]: negative trait bounds are not yet fully implemented; use marker types for now`
