Review comment:
>Make the logic more clear.
If can not split, then we do not need to get tableRegionsCount and
sizeToCheck in IncreasingToUpperBoundRegionSplitPolicy, and also avoid other
comparsion in loop too.
That's a problem for IncreasingToUpperBoundRegionSplitPolicy. We shouldn't
penalise a parent class because of subclasses implementation specifics. And you
are already overriding this method on IncreasingToUpperBoundRegionSplitPolicy
to do the extra loop anyways, so why keep this extra, needless loop here?
