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.
