This massively reduces the number of schedules tried for the litmus
tests, as expected, which is great! Interestingly, it does result in
more unique results being discovered for intelWP27 and intelWP28. This
is surprising DPOR is supposed to be complete. Perhaps this indicates
some unsoundness in the way I have integrated schedule bounding with
relaxed memory.
For some reason, this causes significantly more schedules to be explored
in some of the litmus tests, in particular intelWP27 and intelWP28. I've
not dug too deeply, but it's probably something which should be
addresed.
