r=saethlin Extending `#[rustc_force_inline]` to be applicable to inherent methods `#[rustc_force_inline]` is an internal-only attribute similar to `#[inline(always)]` but which emits an error if inlining cannot occur. rustc_force_inline uses the MIR inliner to do this and has limitations on where it can be applied to ensure that an error is always emitted if inlining can't happen (e.g. it can't be applied to trait methods because calls to those can't always be resolved). `#[rustc_force_inline]` is motivated by AArch64 pointer authentication intrinsics where it is vital for the security properties of these intrinsics that they do not exist in standalone functions that could be used as gadgets in an exploit (if they could, then you could sign whatever pointers you want, for example, which is bad, but if you force inlining, then you can't jump to a reusable function containing only these instructions). Since its initial implementation, `#[rustc_force_inline]` could only be applied to free functions. This can be relaxed to also allow inherent methods while still preserving the desired properties. In a work-in-progress patch for manual pointer authentication intrinsics, it is useful to introduce types with inherent methods that would need to be force inlined. r? `@saethlin`

- Changes parser to allow application to inherent methods. - Adds tests to confirm extended functionality works just as the existing.

Add an attribute to check the number of lanes in a SIMD vector after monomorphization Allows std::simd to drop the `LaneCount<N>: SupportedLaneCount` trait and maintain good error messages. Also, extends rust-lang/rust#145967 by including spans in layout errors for all ADTs. r? ``@RalfJung`` cc ``@workingjubilee`` ``@programmerjake``

initial implementation of the darwin_objc unstable feature Tracking issue: https://github.com/rust-lang/rust/issues/145496 This feature makes it possible to reference Objective-C classes and selectors using the same ABI used by native Objective-C on Apple/Darwin platforms. Without it, Rust code interacting with Objective-C must resort to loading classes and selectors using costly string-based lookups at runtime. With it, these references can be loaded efficiently at dynamic load time. r? ```@tmandry``` try-job: `*apple*` try-job: `x86_64-gnu-nopt`

r=jdonszelmann,ralfjung,traviscross Implement `#[rustc_align_static(N)]` on `static`s Tracking issue: https://github.com/rust-lang/rust/issues/146177 ```rust #![feature(static_align)] #[rustc_align_static(64)] static SO_ALIGNED: u64 = 0; ``` We need a different attribute than `rustc_align` because unstable attributes are tied to their feature (we can't have two unstable features use the same unstable attribute). Otherwise this uses all of the same infrastructure as `#[rustc_align]`. r? `@traviscross`
