This is a tracking issue for volatile operations in const.
Public API
// core::ptr
pub const unsafe fn read_volatile<T>(src: *const T) -> T;

impl<T> *const T {
pub const unsafe fn read_volatile(self) -> T;
}
impl<T> *mut T {
pub const unsafe fn read_volatile(self) -> T;
pub const unsafe fn write_volatile(self, val: T);
}
impl<T> NonNull<T> {
pub const unsafe fn read_volatile(self) -> T;
pub const unsafe fn write_volatile(self, val: T);
