2022-08-29Rollup merge of #99027 - tmiasko:basic-blocks, r=oli-obkMatthias Krüger-17/+14
Replace `Body::basic_blocks()` with field access Since the refactoring in #98930, it is possible to borrow the basic blocks independently from other parts of MIR by accessing the `basic_blocks` field directly. Replace unnecessary `Body::basic_blocks()` method with a direct field access, which has an additional benefit of borrowing the basic blocks only.

2022-07-20Auto merge of #99058 - michaelwoerister:remove-stable-set-and-map, r=nagisabors-1/+1
Remove the unused StableSet and StableMap types from rustc_data_structures. The current implementation is not "stable" in the same sense that `HashStable` and `StableHasher` are stable, i.e. across compilation sessions. So, in my opinion, it's better to remove those types (which are basically unused anyway) than to give the wrong impression that these are safe for incr. comp. I plan to provide new "stable" collection types soon that can be used to replace `FxHashMap` and `FxHashSet` in query results (see [draft](https://github.com/michaelwoerister/rust/commit/69d03ac7a7d651a397ab793e9d78f8fce3edf7a6)). It's unsound that `HashMap` and `HashSet` implement `HashStable` (see https://github.com/rust-lang/rust/issues/98890 for a recent P-critical bug caused by this) -- so we should make some progress there.

2022-07-16Rollup merge of #98582 - oli-obk:unconstrained_opaque_type, r=estebankMatthias Krüger-0/+1
Allow destructuring opaque types in their defining scopes fixes #96572 Before this PR, the following code snippet failed with an incomprehensible error, and similar code just ICEd in mir borrowck. ```rust type T = impl Copy; let foo: T = (1u32, 2u32); let (a, b) = foo; ``` The problem was that the last line created MIR projections of the form `foo.0` and `foo.1`, but `foo`'s type is `T`, which doesn't have fields (only its hidden type does). But the pattern supplies enough type information (a tuple of two different inference types) to bind a hidden type.
