I suggest placing it next to the gem_execbuf().
Just convenience in balancing mode so that nr(VCS) = nr(VCS1) + nr(VCS2). Also from a different angle, if the sum does not hold, that means workload had auto-balancing and explicit VCS1/2 batches. It's only used to print out the stats at the end of the run.
