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 05:56:38 -05:00			`#![feature(negative_impls)]`

Fallout: tests. As tests frequently elide things, lots of changes here. Some of this may have been poorly rebased, though I tried to be careful and preserve the spirit of the test. 2015-02-12 10:29:52 -05:00			`trait TestTrait {`
