embedding debugger visualizers into a generated PDB.
Cleanup `DebuggerVisualizerFile` type and other minor cleanup of queries.
Merge the queries for debugger visualizers into a single query.
Revert move of `resolve_path` to `rustc_builtin_macros`. Update dependencies in Cargo.toml for `rustc_passes`.
Respond to PR comments. Load visualizer files into opaque bytes `Vec<u8>`. Debugger visualizers for dynamically linked crates should not be embedded in the current crate.
Update the unstable book with the new feature. Add the tracking issue for the debugger_visualizer feature.
Respond to PR comments and minor cleanups.

Using an obviously-placeholder syntax. An RFC would still be needed before this could have any chance at stabilization, and it might be removed at any point.
But I'd really like to have it in nightly at least to ensure it works well with try_trait_v2, especially as we refactor the traits.

Stabilize `derive_default_enum`
This stabilizes `#![feature(derive_default_enum)]`, as proposed in [RFC 3107](https://github.com/rust-lang/rfcs/pull/3107) and tracked in #87517. In short, it permits you to `#[derive(Default)]` on `enum`s, indicating what the default should be by placing a `#[default]` attribute on the desired variant (which must be a unit variant in the interest of forward compatibility).

* split `fuzzy_provenance_casts` into a ptr2int and a int2ptr lint
* feature gate both lints
* update documentation to be more realistic short term
* add tests for these lints

Add the generic_associated_types_extended feature
Right now, this only ignore obligations that reference new placeholders in `poly_project_and_unify_type`. In the future, this might do other things, like allowing object-safe GATs.
**This feature is *incomplete* and quite likely unsound. This is mostly just for testing out potential future APIs using a "relaxed" set of rules until we figure out *proper* rules.**
Also drive by cleanup of adding a `ProjectAndUnifyResult` enum instead of using a `Result<Result<Option>>`.

Stabilise `aarch64_target_feature`

[1/2] Implement macro meta-variable expressions
See https://github.com/rust-lang/rust/pull/93545#issuecomment-1050963295
The logic behind `length`, `index` and `count` was removed but the parsing code is still present, i.e., everything is simply ignored like `ignored`.

Treat unstable lints as unknown
This change causes unstable lints to be ignored if the `unknown_lints`
lint is allowed. To achieve this, it also changes lints to apply as soon
as they are processed. Previously, lints in the same set were processed
as a batch and then all simultaneously applied.

Merge `#[deprecated]` and `#[rustc_deprecated]`
The first commit makes "reason" an alias for "note" in `#[rustc_deprecated]`, while still prohibiting it in `#[deprecated]`.
The second commit changes "suggestion" to not just be a feature of `#[rustc_deprecated]`. This is placed behind the new `deprecated_suggestion` feature. This needs a tracking issue; let me know if this PR will be approved and I can create one.
The third commit is what permits `#[deprecated]` to be used when `#![feature(staged_api)]` is enabled. This isn't yet used in stdlib (only tests), as it would require duplicating all deprecation attributes until a bootstrap occurs. I intend to submit a follow-up PR that replaces all uses and removes the remaining `#[rustc_deprecated]` code after the next bootstrap.

Update tracking issue numbers for inline assembly sub-features
The main tracking issue for inline assembly is [closed](https://github.com/rust-lang/rust/issues/72016#issuecomment-1022332954), further tracking of the remaining sub-features has been moved to separate tracking issues.

This was not intended to be stabilized yet.

This thus still makes it technically possible to enable the feature, and thus
to trigger UB without `unsafe`, but this is fine since incomplete features are
known to be potentially unsound (labelled "may not be safe").
This follows from the discussion at https://github.com/rust-lang/rust/pull/93176#discussion_r799413561

PatchMixolydic:where-in-the-world-is-const_fn_trait_bound, r=oli-obk
Update tracking issue for `const_fn_trait_bound`
It previously pointed to #57563, the conglomerate issue for `const fn` (presumably under the feature gate `const_fn`). This tracking issue doesn't mention anything about `const_fn_trait_bound`(the only occurrence of "trait bound" is for the now-removed `?const Trait` syntax), which can be confusing to people who want to find out more about trait bounds on `const fn`s. This pull request changes the tracking issue to one meant specifically for `const_fn_trait_bound`, #93706, which can help collect information on this feature's stabilization and point users towards `const_trait_impl` if they're looking for const-in-const-contexts trait bounds.
Fixes #93679.

`const fn` (presumably under the feature gate `const_fn`).
`const_fn_trait_bounds` weren't mentioned here, so this commit changes
its tracking issue to a new one.

Also prevent ICE when adding a const in associated const equality.

Create rustdoc_internals feature gate
As suggested by ``@camelid`` [here](https://github.com/rust-lang/rust/pull/90398#issuecomment-955093851), since `doc_keyword` and `doc_primitive` aren't meant to be stabilized, we could put them behind a same feature flag.
This is pretty much what it would look like (needs to update the tests too).
The tracking issue is https://github.com/rust-lang/rust/issues/90418.
What do you think ``@rust-lang/rustdoc`` ?
