interpret/validity: debug-check ScalarPair layout information
This would have caught https://github.com/rust-lang/rust/issues/96158.
I ran the Miri test suite and it still passes.

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.
Update `int_roundings` methods from feedback
This updates `#![feature(int_roundings)]` (#88581) from feedback. All methods now take `NonZeroX`. The documentation makes clear that they panic in debug mode and wrap in release mode.

changelog: move trait_duplication_in_bounds and type_repetition_in_bounds to nursery temporarily. This could already be reverted before the release. Check the Clippy in the Rust repo beta branch when writing this changelog.
Those lints are trait_duplication_in_bounds and
type_repetition_in_bounds. I don't think those can be fixed on the
Clippy side alone, but need changes in the compiler. So let's move them
to nursery to get the sync through and then fix them on the rustc side.
Also adds a regression test that has to be fixed before they can be
moved back to pedantic.
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.
Avoid using `rand::thread_rng` in the stdlib benchmarks.
This is kind of an anti-pattern because it introduces extra nondeterminism for no real reason. In thread_rng's case this comes both from the random seed and also from the reseeding operations it does, which occasionally does syscalls (which adds additional nondeterminism). The impact of this would be pretty small in most cases, but it's a good practice to avoid (particularly because avoiding it was not hard).
Anyway, several of our benchmarks already did the right thing here anyway, so the change was pretty easy and mostly just applying it more universally. That said, the stdlib benchmarks aren't particularly stable (nor is our benchmark framework particularly great), so arguably this doesn't matter that much in practice.
~~Anyway, this also bumps the `rand` dev-dependency to 0.8, since it had fallen somewhat out of date.~~ Nevermind, too much of a headache.
Enable tracing for all queries
This allows you to log everything within a specific query, e.g.
```
env RUSTC_LOG=[mir_borrowck]
```
dumping all borrowck queries may be a bit verbose, so you can also restrict it to just an item of your choice:
```
env RUSTC_LOG=[mir_borrowck{key=\.\*name_of_item\.\*}]
```
the regex `.*` in the key name are because the key is a debug printed DefId, so you'd get all kinds of things like hashes in there. The tracing logs will show you the key, so you can restrict it further if you want.
Relax memory ordering used in SameMutexCheck
`SameMutexCheck` only requires atomicity for `self.addr`, but does not need ordering of other memory accesses in either the success or failure case. Using `Relaxed`, the code still correctly handles the case when two threads race to store an address.
Relax memory ordering used in `min_stack`
`min_stack` does not provide any synchronization guarantees to its callers, and only requires atomicity for `MIN` itself, so relaxed memory ordering is sufficient.
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.
