rustdoc: linking to a local proc macro no longer warns
fixes https://github.com/rust-lang/rust/issues/91274
tried to keep the fix general in case we ever have any other kind of item that occupies
multiple namespaces simultaniously.
Improve intrinsic handling in cg_ssa
* Move all intrinsic handling code to the start of `codegen_call_terminator`.
* Push some intrinsic handling code into `codegen_intrinsic_call`.
* Don't depend on FnAbi for intrinsics.
Split `autodiff` into `autodiff_forward` and `autodiff_reverse`
This PR splits `#[autodiff]` macro so `#[autodiff(df, Reverse, args)]` would become `#[autodiff_reverse(df, args)]` and `#[autodiff(df, Forward, args)]` would become `#[autodiff_forwad(df, args)]`.
Add data_ptr method to Mutex and RwLock
Implementation of https://github.com/rust-lang/rust/issues/140368 / https://github.com/rust-lang/libs-team/issues/531.
I tried to write a useful safety section about when it is safe to read or write through the returned pointers, but couldn't come up with something nice. Hoping this PR is still useful without that. I'm happy to add any doc strings other people come up with if needed before merge, of course.
Unresolved questions:
- Return a `LockResult` or not?
- Return `*mut T` like existing APIs (`Cell::as_ptr` / `MaybeUninit::as[_mut]_ptr` / `Vec::as_ptr` / ...) or be more precise and return `NonNull<T>`?
Would otherwise fail on:
```
thread 'fs::tests::test_eq_windows_file_type' panicked at library/std/src/test_helpers.rs:53:20:
called `Result::unwrap()` on an `Err` value: Os { code: 5, kind: PermissionDenied, message: "Access is denied." }
```
This came from the read-only attribute set on the test file. In order to
fix this, instead of simply disabling the test, the attribute is reset
before the test's end so it may still run successfully.

This does not fully fix things, but it introduces a function that can be used to fix occurences.
When using `to_def` functionality, the input node needs to come from the macro expanded include, not the real file that was included.
This does unfortunately add more caller burden, but there is not really a way around it.
Disable libunwind cross-architecture unwinding
Building with _LIBUNWIND_IS_NATIVE_ONLY disables code for cross-architecture unwinding 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
So they match the order of the parts in the source code, e.g.:
```
struct Foo<T, U> { t: T, u: U }
<-><----> <------------>
/ | \
ident generics variant_data
```
