Revert "Remove `#![feature(never_type)]` from tests." This reverts commit 8f6197f39f7d468dfc5b2bd41dae4769992a2f83. 2019-12-11 08:51:28 -06:00			`#![feature(never_type)]`

stabilise feature(never_type) Replace feature(never_type) with feature(exhaustive_patterns). feature(exhaustive_patterns) only covers the pattern-exhaustives checks that used to be covered by feature(never_type) 2018-01-21 02:44:41 -06:00			`fn foo() -> Result<u32, !> {`
			`Ok(123)`
			`}`
check_match: don't treat privately uninhabited types as uninhabited Fixes #38972. 2017-02-20 11:18:31 -06:00
