Rollup merge of #105806 - mejrs:eager2, r=davidtwco 
Support eager subdiagnostics again

See https://github.com/rust-lang/rust/pull/104941#discussion_r1051135746

I'm not sure how to add a test for this. But I did pick some of the diagnostic structs in the mentioned PR and it works with them.

222d1ff68d Auto merge of #105603 - oli-obk:non_repeatable_queries, r=petrochenkov 
Harden the pre-tyctxt query system against accidental recomputation

While the current compiler has no issues where we `take` and then compute the query again, in https://github.com/rust-lang/rust/pull/105462 I accidentally introduced such a case.

I also took the opportunity to remove `peek_mut`, which is only ever used for `global_tcx` to then invoke `enter`. I added an `enter` method directly on the query.

Rollup merge of #103800 - danielhenrymantilla:stabilize-pin-macro, r=dtolnay 
Stabilize `::{core,std}::pin::pin!`

As discussed [over here](https://github.com/rust-lang/rust/issues/93178#issuecomment-1295843548), it looks like a decent time to stabilize the `pin!` macro.

### Public API

```rust
// in module `core::pin`

/// API: `fn pin<T>($value: T) -> Pin<&'local mut T>`
pub macro pin($value:expr $(,)?) {
    …
}
```

  - Tracking issue: #93178

(now all this needs is an FCP by the proper team?)

Rollup merge of #106532 - compiler-errors:dyn-star-to-dyn, r=jackh726 
Allow codegen to unsize `dyn*` to `dyn`

`dyn* Trait` is just another type that implements `Trait`, so we should be able to unsize `&dyn* Trait` into `&dyn Trait` perfectly fine, same for `Box` and other unsizeable types.

note: Alternatively we could filter out error where-clauses during param-env construction? But we still need to filter out impls with errors during `match_impl`, I think.

Rollup merge of #106167 - yanchen4791:issue-105544-fix, r=oli-obk 
Fix invalid syntax and incomplete suggestion in impl Trait parameter type suggestions for E0311

Fixes #105544

The problems: The suggestion given for E0311 has invalid syntax when the synthetic type parameter is used for Trait type in function declaration:
```rust
fn foo(d: impl Sized) -> impl Sized
```
instead of explicitly specified like the following:
```rust
fn foo<T: Sized>(d: T) -> impl Sized
```
In addition to the syntax error, the suggestions given for E0311 are not complete when multiple elided lifetimes are involved in lifetime bounds, not all involved parameters are given the named lifetime in the suggestions. For the following test case:
```
fn foo(d: impl Sized, p: &mut ()) -> impl Sized + '_ {
    (d, p)
}
```
a good suggestion should add the lifetime 'a to both d and p, instead of d only:
```
fn foo<'a>(d: impl Sized + 'a, p: &'a mut ()) -> impl Sized + '_ {
    (d, p)
}
```

The Solution: Fix the syntax problem in the suggestions when synthetic type parameter is used, and also add lifetimes for all involved parameters.
