Remove existing special atomic rules from kcsan_is_atomic_special() because they are no longer needed. Since we rely on the compiler emitting instrumentation distinguishing volatile accesses, the rules have become redundant. Let's keep kcsan_is_atomic_special() around, so that we have an obvious place to add special rules should the need arise in future.
