By generating a helper function for these, we can keep the atomic expression pre-statement-free. This can help prevent for-loops from being transformed into while loops, which can upset FXC. We can't do the same for workgroup storage atomics, as the InterlockedXXX() methods have the workgroup-storage expression as the first argument, and I'm not aware of any way to make a user-declared parameter be `groupshared`.
