Ben Clayton 9569e2c790 writer/msl: Emit helper functions for atomicCompareExchangeWeak
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.

Ben Clayton e6d171ac66 writer/hlsl: Implement atomics
Storage buffers are emitted as `ByteAddressBuffer`s in HLSL, so we have to jump through hoops to support atomic ops on storage buffer atomics.
Workgroup atomics are far more conventional, but very little code can be shared between these two code paths.
