The parent WF of this instruction is exiting, therefore it should not participate in this barrier any longer. This prevents possible deadlock issues if WFs exit early.
If all WFs have finished, and hence the WG has finished, then we can free up the barrier belonging to the parent WG, but only if we actually used a barrier (i.e., more than one WF in the WG).
Last wavefront of the workgroup has executed return. If the workgroup is not the final one in the kernel, then simply retire it; however, if it is the final one (i.e., indicating the kernel end) then release operation is needed.
If a kernel end and release needed, inject a memory sync and retire the workgroup after receving all acks.
