Hierarchical RegionNode successor iterator.

This iterator iterates over all successors of a RegionNode.

For a BasicBlock RegionNode it skips all BasicBlocks that are not part of the parent Region. Furthermore for BasicBlocks that start a subregion, a RegionNode representing the subregion is returned.

For a subregion RegionNode there is just one successor. The RegionNode representing the exit of the subregion.
