Don't duplicate workgroup for derivatives
...
* Because SPIR-V is SSA, we can use the current workgroup for all cross-group
operations, knowing that the output ID of any such opcode can't also be the
input (so doing workgroup operations one-at-a-time is still fine, we won't
corrupt results of later threads by updating earlier ones.
