Some of the runs had --use-locals-vars enabled, some didn't.  The point of
the initial series of benchmarks Samrith ran was to quantify what affect
the existing optimization levels/grades had.

We'll look into --use-local-vars more closely next week.

The benchmarking of the finite domain solvers was done with
--use-local-vars.
