Atomic.intOr

Performs an atomic bitwise 'or' of the value of @atomic and @val, storing the result back in @atomic.

Think of this operation as an atomic version of { tmp = *atomic; *atomic |= val; return tmp; }.

This call acts as a full compiler and hardware memory barrier.

While @atomic has a volatile qualifier, this is a historical artifact and the pointer passed to it should not be volatile.
