Tobias Grosser ecd4694458 Fix DFS number calculation for postdominators
The DFS number calculation for postdominators was broken. In the case of
multiple exits that form the post dominator root nodes, do not iterate over
all exits, but start from the virtual root node. Otherwise bbs, that are not
post dominated by any exit but by the virtual root node, will never be assigned
a DFS number.
