Rollup merge of #115473 - gurry:113110-expected-item, r=compiler-errors 
Add explanatory note to 'expected item' error

Fixes #113110

It changes the diagnostic from this:

```
error: expected item, found `5`
 --> ../test.rs:1:1
  |
1 | 5
  | ^ expected item
 ```
to this:
```
error: expected item, found `5`
 --> ../test.rs:1:1
  |
1 | 5
  | ^ expected item
  |
  = note: items are things that can appear at the root of a module
  = note: for a full list see https://doc.rust-lang.org/reference/items.html
```

Make if let guard parsing consistent with normal guards

- Add tests that struct expressions are not allowed in `if let` and `while let` (no change, consistent with `if` and `while`)
- Allow struct expressions in `if let` guards (consistent with `if` guards).

Rollup merge of #114704 - bvanjoi:fix-114636, r=compiler-errors 
parser: not insert dummy field in struct

Fixes #114636

This PR eliminates the dummy field, initially introduced in #113999, thereby enabling unrestricted use of `ident.unwrap()`. A side effect of this action is that we can only report the error of the first macro invocation field within the struct node.

An alternative solution might be giving a virtual name to the macro, but it appears more complex.(https://github.com/rust-lang/rust/issues/114636#issuecomment-1670228715). Furthermore, if you think https://github.com/rust-lang/rust/issues/114636#issuecomment-1670228715 is a better solution, feel free to close this PR.

Gracefully handle ternary operator

Fixes #112578

~~May not be the best way to do this as it doesn't check for a single `:`, so it could perhaps appear even when the actual issue is just a missing semicolon. May not be the biggest deal, though?~~

Nevermind, got it working properly now ^^

Rollup merge of #111181 - bvanjoi:fix-issue-111148, r=davidtwco 
fix(parse): return unpected when current token is EOF

close https://github.com/rust-lang/rust/issues/111148

#111148 panic occurred because [FatalError.raise()](https://github.com/bvanjoi/rust/blob/master/compiler/rustc_parse/src/parser/mod.rs#LL540C3-L540C3) was encountered which caused by `Eof` and `Pound`(the last token) had same span, when parsing `#` in `fn a<<i<Y<w<>#`.

<img width="825" alt="image" src="https://user-images.githubusercontent.com/30187863/236612589-9e2c6a0b-18cd-408c-b636-c12a51cbcf1c.png">

There are a few ways to solve this problem:

- Change the action assign for [self.last_unexpected_token_span](https://github.com/rust-lang/rust/blob/master/compiler/rustc_parse/src/parser/diagnostics.rs#L592), for example, if current token is `Eof`, then return Error directly.
- Avoid triggering the `FatalError` when the current token is `Eof`.

I have chosen the second option because executing `expected_one_of_not_found` when the token is `Eof` but not in `ediable` seems reasonable.
