Does this affect any tools or backends? (modulo their tests, I just mean the tool/backend code) |
From a quick skim over them the tools and backends look fine as they don't use any features I classified as internal, but I'll make sure that they're fine when marking this as ready. |

It lints against features that are inteded to be internal to the compiler and standard library. Implements MCP rust-lang#596. We allow `internal_features` in the standard library and compiler as those use many features and this _is_ the standard library from the "internal to the compiler and standard library" after all. Marking some features as internal wasn't exactly the most scientific approach, I just marked some mostly obvious features. While there is a categorization in the macro, it's not very well upheld (should probably be fixed in another PR). We always pass `-Ainternal_features` in the testsuite About 400 UI tests and several other tests use internal features. Instead of throwing the attribute on each one, just always allow them. There's nothing wrong with testing internal features^^

Add allow(internal_features) rust-lang/rust#108955 has added a new deny-by-default lint to reject internal features, which is causing tests to fail on nightly. This adds an `allow` to work around that.
Add `internal_features` lint Implements rust-lang/compiler-team#596 Also requires some more test blessing for codegen tests etc `@jyn514` had the idea of just `allow`ing the lint by default in the test suite. I'm not sure whether this is a good idea, but it's definitely one worth considering. Additional input encouraged.
