2021-04-02Auto merge of #80828 - SNCPlay42:opaque-projections, r=estebankbors-3/+3
Fix expected/found order on impl trait projection mismatch error fixes #68561 This PR adds a new `ObligationCauseCode` used when checking the concrete type of an impl trait satisfies its bounds, and checks for that cause code in the existing test to see if a projection's normalized type should be the "expected" or "found" type. The second commit adds a `peel_derives` to that test, which appears to be necessary in some cases (see projection-mismatch-in-impl-where-clause.rs, which would still give expected/found in the wrong order otherwise). This caused some other changes in diagnostics not involving impl trait, but they look correct to me.

Do not ICE when evaluating locals' types of invalid `yield` When a `yield` is outside of a generator, check its value regardless to avoid an ICE while trying to get all locals' types in writeback. Fix #78653.

2020-11-23Rename `optin_builtin_traits` to `auto_traits`Camelid-1/+1
They were originally called "opt-in, built-in traits" (OIBITs), but people realized that the name was too confusing and a mouthful, and so they were renamed to just "auto traits". The feature flag's name wasn't updated, though, so that's what this PR does. There are some other spots in the compiler that still refer to OIBITs, but I don't think changing those now is worth it since they are internal and not particularly relevant to this PR. Also see <https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/opt-in.2C.20built-in.20traits.20(auto.20traits).20feature.20name>.
