Fix typo in `offset_from` documentation
Small fix for what I think is a typo in the `offset_from` documentation.
Someone reading this may understand that the distance in bytes is obtained by dividing the distance by `mem::size_of::<T>()`, but here we just want to define "units of T" in terms of bytes (i.e., units of T == bytes / `mem::size_of::<T>()`).
Bootstrap currently provides `-Zunstable-options` for OpenBSD when using
split debuginfo - this commit provides it for all BSD targets.

The logic around handling co-inductive cycles in the evaluation cache
is confusing and error prone. Fortunately, a perf run showed that it
doesn't actually appear to improve performance, so we can simplify
this code (and eliminate a source of ICEs) by just skipping caching
the evaluation results for co-inductive cycle participants.
This commit makes no changes to any of the other logic around
co-inductive cycle handling. Thus, while this commit could
potentially expose latent bugs that were being hidden by
caching, it should not introduce any new bugs.
* If it's just `-> a`, use "In Function Return Types"
* If it's just `a b`, use "In Function Parameters"
* Otherwise, still use "In Function Signatures"

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.
