- `AtomicPtr::fetch_ptr_{add,sub}`
- `AtomicPtr::fetch_byte_{add,sub}`
- `AtomicPtr::fetch_{or,and,xor}`
These APIs are compatible with strict-provenance on `cfg(miri)`.
Otherwise, they are compatible with permissive-provenance.
Once `#![feature(strict_provenance_atomic_ptr)]` is stabilized,
these APIs will be strict-provenance compatible in all cases from the
version in which it is stabilized.
