When a TSY barrier is hit, the entire supergroup will be synchronized. If the supergoup is large and uses all available QPU threads it would mean that we would sychronize and stall all running threads until all of them reach the barrier, which may be inefficient. This patch makes it so that if the compute shader has any such barriers we limit the supergroup size so each supergroup only takes half of the QPU threads available at most, so that if one supergroup hits a barrier we have at least one other supergroup we can run, reducing idle QPU time.
