1f4b630899 add auto keyword, parse auto trait, lower to HIR
Adds an `IsAuto` field to `ItemTrait` which flags if the trait was
declared as an `auto trait`.

Auto traits cannot have generics nor super traits.

06506bb751 [Syntax Breaking] Rename DefaultImpl to AutoImpl
DefaultImpl is a highly confusing name for what we now call auto impls,
as in `impl Send for ..`. The name auto impl is not formally decided
but for sanity anything is better than `DefaultImpl` which refers
neither to `default impl` nor to `impl Default`.

59d484575a Auto merge of #45569 - zackmdavis:unexported_pub_lint, r=petrochenkov
`unreachable-pub` lint (as authorized by RFC 2126)

To whom it may concern:

RFC 2126 commissions the creation of a lint for `pub` items that are not visible from crate root (#45521). We understand (but seek confirmation from more knowledgable compiler elders) that this can be implemented by linting HIR items that are _not_ ~~`cx.access_levels.is_exported`~~ `cx.access_levels.is_reachable` but have a `vis` (-ibility) field of `hir::Visibility::Public`.

The lint, tentatively called ~~`unexported-pub`~~ `unreachable-pub` (with the understanding that much could be written on the merits of various names, as it is said of the colors of bicycle-sheds), suggests `crate` as a replacement for `pub` if the `crate_visibility_modifier` feature is enabled (see #45388), and `pub(crate)` otherwise. We also use help messaging to suggest the other potential fix of exporting the item; feedback is desired as to whether this may be confusing or could be worded better.

As a preview of what respecting the proposed lint would look like (and to generate confirmatory evidence that this implementation doesn't issue false positives), ~~we take its suggestions for `libcore`~~ (save one, which is deferred to another pull request because it brings up an unrelated technical matter). I remain your obedient servant.

r? @rust-lang/infra

This is just an emergency fix to keep bors running for another week. I think the numbers will be broken soon. Can we verify if this statement is still true later?

a7d98c7837 Auto merge of #45630 - joshleeb:iss35241, r=estebank
Improve display of error E0308

Ref. Forgetting to call a variant constructor causes a confusing error message #35241.

This PR modifies [`note_type_err`](b7041bfab3/src/librustc/infer/error_reporting/mod.rs (L669-L674)) to display a `help` message when a `TyFnPtr` or `TyFnDef` are found and the return type, of the function or function pointer, is the same as the type that is expected.

The output of compiling

```rust
struct Foo(u32);

fn test() -> Foo { Foo }

fn main() {}
```

is now

```bash
$ rustc src/test/ui/issue-35241.rs
error[E0308]: mismatched types
