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.

Rollup merge of #111449 - compiler-errors:recover-impl-generics-correctly, r=Nilstrieb 
Recover `impl<T ?Sized>` correctly

Fixes #111327

r? ````@Nilstrieb```` but you can re-roll

Alternatively, happy to close this if we're okay with just saying "sorry #111327 is just a poor side-effect of parser ambiguity" 🤷

Rollup merge of #110694 - est31:builtin, r=petrochenkov 
Implement builtin # syntax and use it for offset_of!(...)

Add `builtin #` syntax to the parser, as well as a generic infrastructure to support both item and expression position builtin syntaxes. The PR also uses this infrastructure for the implementation of the `offset_of!` macro, added by #106934.

Rollup merge of #108161 - WaffleLapkin:const_param_ty, r=BoxyUwU 
Add `ConstParamTy` trait

This is a bit sketch, but idk.
r? `@BoxyUwU`

Yet to be done:
- [x] ~~Figure out if it's okay to implement `StructuralEq` for primitives / possibly remove their special casing~~ (it should be okay, but maybe not in this PR...)
- [ ] Maybe refactor the code a little bit
- [x] Use a macro to make impls a bit nicer

Future work:
- [ ] Actually™ use the trait when checking if a `const` generic type is allowed
- [ ] _Really_ refactor the surrounding code
- [ ] Refactor `marker.rs` into multiple modules for each "theme" of markers

If you think we live too much then
You can sacrifice diagnostics
Don't mix your garbage
Into my syntax
So many weird hacks keep diagnostics alive
Yet I don't even step outside
So many bad diagnostics keep tyasc alive
Yet tyasc doesn't even bother to survive!
