Function atomic_or

pub unsafe fn atomic_or<I: Integer, const SCOPE: u32, const SEMANTICS: u32>(
    ptr: &mut I,
    value: I,
) -> I

Perform the following steps atomically with respect to any other atomic accesses within Scope to the same location:

1. Load through ptr to get an original value,
2. Get a new value by the bitwise OR of the original value and value, and
3. Store the new value back through ptr.

The result is the original value.
