`concat_idents!` was deprecated in [1] and will be removed in the near
future. rust-analyzer's support is independent of rustc's, so drop RA
support now to make syncing easier.

Building with _LIBUNWIND_IS_NATIVE_ONLY disables code for cross-architecture unwinding
it is disabled by default in LLVM [1], replicate the cmake behavior in bootstrap process
It also enables some additional code that handles PAC-specific unwind info
it helps compiling with the -mbranch-protection=pac or -mbranch-protection=standard flags
This fixes build with clang/musl on aarch64

Bump master `stage0` compiler
To include beta backport of revert rust-lang/rust#141024 which should undo linker warnings during bootstrapping of Windows MSVC targets due to rust-lang/rust#140176.

rustdoc: use descriptive tooltip if doctest is conditionally ignored

here's what it looks like now:

Make check-cfg diagnostics work in `#[doc(cfg(..))]`
This PR makes it so that the check-cfg `unexpected_cfgs` lint, is correctly emitted in `rustdoc`'s `#[doc(cfg(..))]`.
This is achieved by adding a custom trait to `cfg_matches` (the method that emits the lint) which permits `rustc` and `rustdoc` to each have their way to emitting lints (via buffered lints/AST for `rustc` and via `TyCtxt`/HIR for `rustdoc`).
The reason this is required is because buffered lints operates on the AST but `rustdoc` uses the HIR and by the time `rustdoc` calls `cfg_matches` we are way passed the point where buffered lints have been drain and emitted.

add `asm_cfg`: `#[cfg(...)]` within `asm!`
tracking issue: https://github.com/rust-lang/rust/issues/140364
blocked on: https://github.com/rust-lang/rust/pull/140490
This feature was discussed in https://github.com/rust-lang/rust/issues/140279. It allows configuring templates and operands in the assembly macros, for example:
```rust
asm!( // or global_asm! or naked_asm!
"nop",
#[cfg(target_feature = "sse2")]
"nop",
// ...
#[cfg(target_feature = "sse2")]
a = const 123, // only used on sse2
);
```
r? `@tgross35`
cc `@traviscross` `@Amanieu`
Now builds on https://github.com/rust-lang/rust/pull/140490, which should be merged first.

Add some track_caller info to precondition panics
Currently, when you encounter a precondition check, you'll always get the caller location of the implementation of the precondition checks. But with this PR, you'll be told the location of the invalid call. Which is useful.
I thought of this while looking at https://github.com/rust-lang/rust/pull/129642#issuecomment-2311703898.
The changes to `tests/ui/const*` happen because the const-eval interpreter skips `#[track_caller]` frames in its backtraces.
The perf implications of this are:
* Increased debug binary sizes. The caller_location implementation requires that the additional data we want to display here be stored in const allocations, which are deduplicated but not across crates. There is no impact on optimized build sizes. The panic path and the caller location data get optimized out.
* The compile time hit to opt-incr-patched bitmaps happens because the patch changes the line number of some function calls with precondition checks, causing us to go from 0 dirty CGUs to 1 dirty CGU.
* The other compile time hits are marginal but real, and due to doing a handful of new queries. Adding more useful data isn't completely free.

bump fluent-* crates
This bumps fluent-* crates, switching to more up-to-date deps, reducing number of old ones.
changelogs is pure refactoring:

Rename `{GenericArg,Term}::unpack()` to `kind()`
A well-deserved rename IMO.

cc `@rust-lang/types,` but I'd be surprised if this is controversial.

This adds running of cargo's tests to the aarch64-apple-darwin job. The
reason for this is that tier-1 targets are ostensibly supposed to run
tests for host tools, but we are not doing that here. We do have fairly
good coverage in Cargo's CI, but we don't have much coverage of beta or
stable. I think it would be good to have a fallback here.

Although they are clickable in the github preview, they aren't in the actual rendered HTML on https://rustc-dev-guide.rust-lang.org/.
This commit fixes that.

With the stage0 refactor the proc_macro version found in the sysroot
will no longer always match the proc_macro version that proc-macros get
compiled with by the rustc executable that uses this proc_macro. This
will cause problems as soon as the ABI of the bridge gets changed to
implement new features or change the way existing features work.
To fix this, this commit changes rustc crates to depend directly on the
local version of proc_macro which will also be used in the sysroot that
rustc will build.

bootstrap: translate Windows paths in a way that works for both Cygwin and MSYS2
Cygwin defaults to rooting Windows paths in /cygdrive/X, while MSYS2 configures them to be /X. Regardless of configuration, drives are always accessible as /proc/cygdrive/X, so use that.
If there are other shells on Windows that are supported and use /X style paths, perhaps something more complicated needs to be done.

Keep the `P` constructor function for now, to minimize immediate churn.
All the `into_inner` calls are removed, which is nice.
|
|
Moving the visibility stuff into the `from_fn` avoids the `Cow` and
makes the code a little shorter and simpler.
|
|
- `ret` only ever gets at most one entry, so it can be an `Option`
instead of a `Vec`.
- Which means we can use `filter_map` instead of `flat_map`.
- Move `trait_` next to the `ret` assignment, which can only happen
once.
- No need for `impls` to be a `Vec`, it can remain an iterator.
- Avoid `Result` when collecting `impls`.
