I guess it wouldn't hurt to show this for exec_size < 4 too even though
it will typically be 1N.

This may cause an assertion failure on SNB and earlier because the
NibCtrl field doesn't exist. You could do something along the lines of:
| const unsigned nib_ctl = devinfo->gen < 7 ? 0 :
| brw_inst_nib_control(devinfo, inst);

The usual qtr_ctl field is still taken into account by the hardware
regardless of whether you use NibCtrl, this should probably be:
| format(file, " %dN", qtr_ctl * 2 + nib_ctl + 1);
