Rollup merge of #65355 - Centril:almost-is-never-enough, r=oli-obk
Stabilize `!` in Rust 1.41.0 This PR stabilizes the `never_type` (written `!`). The type represents computations that we know diverge in the type system and therefore has no values / inhabitants / elements / members. The current nightly version is 1.40.0 which will become stable on 2019-12-19. Tracking issue: https://github.com/rust-lang/rust/issues/35121. Closes https://github.com/rust-lang/rust/issues/57012. Closes https://github.com/rust-lang/rust/issues/58184. Original stabilization report: https://github.com/rust-lang/rust/issues/57012#issuecomment-452398538 Additional notes: - In #62661 we reserved `impl<T> From<!> for T` so this concern should be resolved. - The type inference fallback change is moved to `#![feature(never_type_fallback)]` (https://github.com/rust-lang/rust/issues/65992). - You can find all of the tests referencing `never_type` in this PR which also reorganizes these tests whereas they were more scattered before. r? @nikomatsakis
