Changes looks fine to me.

Memory events (mem-loads and mem-stores) currently use the threshold event selection as issue to finish. Power10 supports issue to complete as part of thresholding which is more appropriate for mem-loads and mem-stores. Hence fix the event code for memory events to use issue to complete.
