rustc: Move stability functionality into queries This commit primarily removes the `stability` field from `TyCtxt` as well as its internal mutable state, instead using a query to build the stability index as well as primarily using queries for other related lookups. Like previous commits the calculation of the stability index is wrapped in a `with_ignore` node to avoid regressing the current tests, and otherwise this commit also introduces #44232 but somewhat intentionally so. 2017-08-31 22:08:34 +00:00			`#![warn(unused_features)]`
Relax restrictions on unknown feature directives Instead of forcibly always aborting compilation, allow usage of #[warn(unknown_features)] and related lint attributes to selectively abort compilation. By default, this lint is deny. 2013-11-26 22:55:06 +00:00
Convert unknown_features lint into an error 2018-07-23 20:05:39 +00:00			`#![allow(stable_features)]`

Removed `#[rustc_error]` from tests that are all `// compile-pass`. I also added `// skip-codegen` to each one, to address potential concerns that this change would otherwise slow down our test suite spending time generating code for files that are really just meant to be checks of compiler diagnostics. (However, I will say: My preference is to not use `// skip-codegen` if one can avoid it. We can use all the testing of how we drive LLVM that we can get...) (Updated post rebase.) 2018-10-31 12:08:01 +00:00			`fn main() {}`
