Currently rules are added to the expression tree in order, and then
tree simplification and factoring is done. This forces simplification
to "search" through the tree to find rules with the same permissions
during right factoring, which dependent on ordering of factoring may
not be able to group all rules of the same permissions.
Instead of having tree factoring do the work to regroup rules with the
same permissions, pregroup them as part of the expr tree construction.
And only build the full tree when the dfa is constructed.
