If you do `derive(PartialEq)` on a packed struct, the output shown by
`-Zunpretty=expanded` includes expressions like this:
```
{ self.x } == { other.x }
```
This is invalid syntax. This doesn't break compilation, because the AST
nodes are constructed within the compiler. But it does mean anyone using
`-Zunpretty=expanded` output as a guide for hand-written impls could get
a nasty surprise.
This commit fixes things by instead using this form:
```
({ self.x }) == ({ other.x })
```

Remove confusing 'while checking' note from opaque future type mismatches
Maybe I'm just misinterpreting the wording of the note. The only value I can see in this note is that it points out where the async's opaque future is coming from, but the way it's doing it is misleading IMO.
For example:
```rust
note: while checking the return type of the `async fn`
--> $DIR/dont-suggest-missing-await.rs:7:24
|
LL | async fn make_u32() -> u32 {
| ^^^ checked the `Output` of this `async fn`, found opaque type
```
We point at the type `u32` in the HIR, but then say "found opaque type". We also say "while checking"... but we're typechecking a totally different function when we get this type mismatch!
r? `@estebank` but feel free to reassign and/or take your time reviewing this. I'd be inclined to also discuss reworking the presentation of this type mismatch to restore some of these labels in a way that makes it more clear what it's trying to point out.
…ambiguous, r=estebank Revert "Teach parser to understand fake anonymous enum syntax" and related commits anonymous enum types are currently ambiguous in positions like: * `|` operator: `a as fn() -> B | C` * closure args: `|_: as fn() -> A | B` I first tried to thread around `RecoverAnonEnum` into all these positions, but the resulting complexity in the compiler is IMO not worth it, or at least worth a bit more thinking time. In the mean time, let's revert this syntax for now, so we can go back to the drawing board.

Add proc-macro boilerplate to crt-static test I was seeing this failure when running ui tests with with a `-Cpanic=abort` stdlib targeting fuchsia: ``` ---- [ui] tests/ui/proc-macro/crt-static.rs stdout ---- normalized stderr: warning: building proc macro crate with `panic=abort` may crash the compiler should the proc-macro panic warning: 1 warning emitted The actual stderr differed from the expected stderr. ``` `force-host` was enough to stop it from running/failing, not sure if I should also add `needs-unwind`?
