This is implemented differently depending on the cluster size:
- At most 8: in this case, executing brcst.active will leave the
reduction in the last invocation of each cluster. Simply iterate the
clusters and broadcast the last invocation to the rest.
- Otherwise, also iterate the clusters but execute the usual
reduce_clusters_ir3 loop for each of them.
