Remove mutable_borrow_reservation_conflict lint and allow the code pattern
This was the only breaking issue with the NLL stabilization PR. Lang team decided to go ahead and allow this.

Improve settings loading strategy
I learned about this thanks to ```@jsha``` who suggested this approach:
It improves the settings loading strategy by loading CSS and JS at the same time to prevent the style to be applied afterwards on slow connections.

Report that opaque types are not allowed in impls even in the presence of other errors
fixes #96569
before this PR those useful errors were hidden because either `unused parameter` or `only traits defined in the current crate can be implemented for arbitrary types` got emitted first.
Add a new Rust attribute to support embedding debugger visualizers
Implemented [this RFC](https://github.com/rust-lang/rfcs/pull/3191) to add support for embedding debugger visualizers into a PDB.
Added a new attribute `#[debugger_visualizer]` and updated the `CrateMetadata` to store debugger visualizers for crate dependencies.

Include nonexported macro_rules! macros in the doctest target
Fixes#88038
This PR aims to include nonexported `macro_rules!` macros in the doctest target. For more details, please see the above issue.
Enable full revision in const generics ui tests
The ICEs no longer occur since https://github.com/rust-lang/rust/pull/95776 so the revisions can be reenabled
Also adds some regression tests for issues that no longer ICE because of it

Revert "Prefer projection candidates instead of param_env candidates for Sized predicates"
Fixes#93262Reopens#89352
This was a hack that seemed to have no negative side-effects at the time. Given that the latter has a workaround and likely less common than the former, it makes sense to revert this change.

Overhaul `MacArgs`
Motivation:
- Clarify some code that I found hard to understand.
- Eliminate one use of three places where `TokenKind::Interpolated` values are created.
r? `@petrochenkov`
The value in `MacArgs::Eq` is currently represented as a `Token`.
Because of `TokenKind::Interpolated`, `Token` can be either a token or
an arbitrary AST fragment. In practice, a `MacArgs::Eq` starts out as a
literal or macro call AST fragment, and then is later lowered to a
literal token. But this is very non-obvious. `Token` is a much more
general type than what is needed.
This commit restricts things, by introducing a new type `MacArgsEqKind`
that is either an AST expression (pre-lowering) or an AST literal
(post-lowering). The downside is that the code is a bit more verbose in
a few places. The benefit is that makes it much clearer what the
possibilities are (though also shorter in some other places). Also, it
removes one use of `TokenKind::Interpolated`, taking us a step closer to
removing that variant, which will let us make `Token` impl `Copy` and
remove many "handle Interpolated" code paths in the parser.
Things to note:
- Error messages have improved. Messages like this:
```
unexpected token: `"bug" + "found"`
```
now say "unexpected expression", which makes more sense. Although
arbitrary expressions can exist within tokens thanks to
`TokenKind::Interpolated`, that's not obvious to anyone who doesn't
know compiler internals.
- In `parse_mac_args_common`, we no longer need to collect tokens for
the value expression.
Quick fix for #96223.
This PR is a quick fix regarding #96223.
As mentioned in the issue, others modification could be added to not elide types with bound vars from suggestions.
Special thanks to ``@jackh726`` for mentoring and ``@Manishearth`` for minimal test case.

Fix flaky rustdoc-ui test because it did not replace time result
As mentioned in https://github.com/rust-lang/rust/pull/93715: a test is flaky because I forgot to replace the time value.

I am suspecting that all unix might be affected, but I am unsure about the right conditional to use. so I only added "openbsd" target inside it as I am able to test it.
rustc nightly built correctly with this PR on openbsd.
When suggesting to import an item, also suggest changing the path if appropriate
When we don't find an item we search all of them for an appropriate
import and suggest `use`ing it. This is sometimes done for expressions
that have paths with more than one segment. We now also suggest changing
that path to work with the `use`.
