Description
Revisit CTS issue https://github.com/KhronosGroup/OpenCL-CTS/issues/939 and the associated PR
https://github.com/KhronosGroup/OpenCL-CTS/pull/941
The summary for the original issue is
" The generator function for atomic_fence uses the current workgroup size to determine the number of non atomic variables per thread. However, when the workgroup size is modified (after the kernel is generated) we don't re-generate the kernel, leading to mismatches during verification."
The PR has been merged but we should revisit to determine if any additional improvements are needed.

Research direction

Determine whether the merged change leaves additional mismatches when the workgroup size changes; done means documenting or addressing any remaining improvements with appropriate CTS validation.
