Rollup merge of rust-lang#108419 - tgross35:atomic-as-ptr, r=m-ou-se

Stabilize `atomic_as_ptr` Fixes rust-lang#66893 This stabilizes the `as_ptr` methods for atomics. The stabilization feature gate used here is `atomic_as_ptr` which supersedes `atomic_mut_ptr` to match the change in rust-lang#107736. This needs FCP. New stable API: ```rust impl AtomicBool { pub const fn as_ptr(&self) -> *mut bool; } impl AtomicI32 { pub const fn as_ptr(&self) -> *mut i32; } // Includes all other atomic types impl<T> AtomicPtr<T> { pub const fn as_ptr(&self) -> *mut *mut T; } ``` r? libs-api `@rustbot` label +needs-fcp
