- Normalize git deps when doing `cargo vendor` for resolving deps inherited from a workspace (rust-lang/cargo#11414)
- Ignore `workspace.default-members` when running `cargo install` on root package of a non-virtual workspace (rust-lang/cargo#11067)
- Corrected documentation of how to cache binaries installed with `cargo install` in CI workflows (rust-lang/cargo#11592)

Don't wf-check non-local RPITs
We were using `ty::is_impl_trait_defn(..).is_none()` to check if we need to add WF obligations for an opaque type.
This is *supposed* to be checking if the type is a TAIT, since RPITs' wfness is implied by wf checking its parent item, but since `is_impl_trait_defn` returns `None` for non-local RPIT and async futures, we unnecessarily consider wf predicates for an RPIT if it is coming from a foreign crate.
Fixes#107036

even more unify Projection/Opaque handling in region outlives code
edit: This continues ate the same pace as #106829. New changes are described in https://github.com/rust-lang/rust/pull/106910#issuecomment-1383251254.
~This touches `OutlivesBound`, `Component`, `GenericKind` enums.~

Remove extra removal from test path
I don't know how to describe it shortly so better show what it's doing instead. Currently, there is one extra "rust/" before the test folder when running tests:
```
failures:
---- [rustdoc] rust/tests/rustdoc/redirect.rs stdout ----
```
This is a bit annoying when copying the test path. This is due to the moving of the `tests` folder one level up, meaning we were trimming too much of the `root_path`.
Now it is again displaying the correct path:
```
failures:
---- [rustdoc] tests/rustdoc/redirect.rs stdout ----
```
document + UI test `E0208` and make its output more user-friendly
Cleans up `E0208`'s output a lot. It could actually be useful for someone learning about variance now. I also added a UI test for it in `tests/ui/error-codes/` and wrote some docs for it.
r? `@GuillaumeGomez` another error code, can't be bothered to find the issue :P. Obviously there's some compiler stuff, so you'll have to hand it off.

make `CastError::NeedsDeref` create a `MachineApplicable` suggestion
Fixes#106903
Simple impl for the linked issue. I also made some other small changes:
- `CastError::ErrorGuaranteed` now owns an actual `ErrorGuaranteed`. This better enforces the static guarantees of `ErrorGuaranteed`.
- `CastError::NeedDeref` code simplified a bit, we now just suggest the `*`, instead of the whole expression as well.
Transform async `ResumeTy` in generator transform
- Eliminates all the `get_context` calls that async lowering created.
- Replace all `Local` `ResumeTy` types with `&mut Context<'_>`.
The `Local`s that have their types replaced are:
- The `resume` argument itself.
- The argument to `get_context`.
- The yielded value of a `yield`.
The `ResumeTy` hides a `&mut Context<'_>` behind an unsafe raw pointer, and the `get_context` function is being used to convert that back to a `&mut Context<'_>`.
Ideally the async lowering would not use the `ResumeTy`/`get_context` indirection, but rather directly use `&mut Context<'_>`, however that would currently lead to higher-kinded lifetime errors.
See <https://github.com/rust-lang/rust/issues/105501>.
The async lowering step and the type / lifetime inference / checking are still using the `ResumeTy` indirection for the time being, and that indirection is removed here. After this transform, the generator body only knows about `&mut Context<'_>`.

Implement `alloc::vec::IsZero` for `Option<$NUM>` types
Fixes#106911
Mirrors the `NonZero$NUM` implementations with an additional `assert_zero_valid`.
`None::<i32>` doesn't stricly satisfy `IsZero` but for the purpose of allocating we can produce more efficient codegen.

Various cleanups around pre-TyCtxt queries and functions
part of #105462
based on https://github.com/rust-lang/rust/pull/106776 (everything starting at [0e2b39f](0e2b39fd1f) is new in this PR)
r? `@petrochenkov`
I think this should be most of the uncontroversial part of #105462.

rustdoc: remove redundant CSS rule `#settings .setting-line`
Since the current version of settings.js always nests things below a div with ID `settings`, this rule always overrode the one above.
