Rollup merge of #118157 - Nadrieril:never_pat-feature-gate, r=compiler-errors
Add `never_patterns` feature gate This PR adds the feature gate and most basic parsing for the experimental `never_patterns` feature. See the tracking issue (https://github.com/rust-lang/rust/issues/118155) for details on the experiment. `@scottmcm` has agreed to be my lang-team liaison for this experiment.
