Previously, we used a plain `Predicate` to cache results (e.g. successes and failures) in ObligationForest. However, fulfillment depends on the precise `ParamEnv` used, so this is unsound in general. This commit changes the impl of `ForestObligation` for `PendingPredicateObligation` to use `ParamEnvAnd<Predicate>` instead of `Predicate` for the associated type. The associated type and method are renamed from 'predicate' to 'cache_key' to reflect the fact that type is no longer just a predicate.

…sper typeck: clarify def_bm adjustments & add tests for or-patterns Clarify the adjustment algorithm for the expected type / default binding-modes when type checking patterns with more documentation and tweaks that make the algorithm more independent of the pattern forms. Also resolve the FIXME noted for or-patterns by deciding that the current implementation is correct, noting the rationale and adding tests for the current implementation. cc rust-lang#54883 r? @oli-obk @varkor
simplify_try: address some of eddyb's comments Addresses only rust-lang#66282 (comment) and rust-lang#66282 (comment). r? @eddyb cc @oli-obk
Fix extra subslice lowering
We are currently ICEing on e.g.
```rust
fn main() {
let [.., b @ ..] = [1, 2];
b;
}
```
This happens because `b @ ..` registers a binding such that `b;` is OK, but then we forget to lower that binding in `rustc_ast_lowering`.
Fixes rust-lang#69103.
