Updated benchmark script to show diff between DM and AR more clearly
* Simply reversed how the stats are displayed in the chart. AR is now
used as a baseline instead of DM. The extra DIFF column now shows how
much faster DM is over AR, rather than how much slower than AR is
compared to DM. For example, instead of displaying that DM takes
0.05x (5%) as much time as AR to perform a task, it will now show AR
takes 20x as long as DM to perform the task. Given that DM is faster
than AR in almost all respects, this is a better way to represent the
differences.
