Add findNearestCommonDominator() for PostDominators.

Add a missing interface to be able to call findNearestCommonDominator
for a PostDominanceTree. The function itself is already implemented in
DominatorTreeBase. The interface however was only added to the
DominatorTree class, but not the PostDominatorClass.
