Previously we were suggesting stuff like `fn f( &u32) {}`To avoid circular link time dependency between core and compiler builtins when building with `-Zshare-generics`.

Fix suggestions for `&a: T` parameters
I've accidentally discovered that we have broken suggestions for `&a: T` parameters:
```rust
fn f(&mut bar: u32) {}
fn main() {
let _ = |&mut a| ();
}
```
```text
error[E0308]: mismatched types
--> ./t.rs:1:6
|
1 | fn f(&mut bar: u32) {}
| ^^^^^^^^-----
| | |
| | expected due to this
| expected `u32`, found `&mut _`
| help: did you mean `bar`: `&u32`
|
= note: expected type `u32`
found mutable reference `&mut _`
error[E0308]: mismatched types
--> ./t.rs:4:23
|
4 | let _: fn(u32) = |&mut a| ();
| ^^^^^--
| | |
| | expected due to this
| expected `u32`, found `&mut _`
| help: did you mean `a`: `&u32`
|
= note: expected type `u32`
found mutable reference `&mut _`
```
It's hard to see, but
1. The help span is overlapping with "expected" spans
2. It suggests `fn f( &u32) {}` (no `mut` and lost parameter name) and `|&u32 ()` (no closing `|` and lost parameter name)
I've tried to fix this.
r? ``@compiler-errors``…n-ice, r=notriddle Fix generic impl rustdoc json output Fixesrust-lang#97986. The problem in case of generic trait impl is that the trait's items are the same for all the types afterward. But since they're the same, it's safe for rustdoc-json to just ignore them. A little representation of what's going on: ```rust trait T { fn f(); // <- defid 0 } impl<Y> T for Y { fn f() {} // <- defid 1 } struct S; // <- defid 1 (since it matches `impl<Y> T for Y` ``` cc ```@Urgau``` r? ```@CraftSpider```

…or, r=estebank Refactor path segment parameter error This PR attempts to rewrite the error handling for an unexpected parenthesised type parameters to: - Use provided data instead of re-parsing the whole span - Add a multipart suggestion to reflect on the changes with an underline - Remove the unnecessary "if" nesting
