r600/sfn: Handle mem barrier and image barrier by using ACK

When reading from and writing to the same image in a shader the
memory_barrier can possibly be handled by emitting an ack-write and then
wait for the ack when the memory barrier is set.

Not sure whow well this goes with the syncronization across all shader
invocations though.
