That is a better solution, agree. Marking all functions as convergent seems to be an overkill to me, but I have created a discardable barrier intrinsic and used it directly in the sub_group_barrier implementation. As expected that helped conformance test to pass.

That said I believe that still makes sense to submit the current change just to connect options we already have defined to their intended functionality.
