Nicolai Haehnle 523f90a2ba [SDA] Bug fix: Use IPD outside the loop as divergence bound ...

Summary:
The immediate post dominator of the loop header may be part of the divergent loop.
Since this /was/ the divergence propagation bound the SDA would not detect joins of divergent paths outside the loop.
