<pre>Michael found by inspection that in rare corner cases the loop we choose to
synthesize SCEVs in the RegionBlockGenerator might be incorrect.
For details see:
<a href="http://reviews.llvm.org/D16522?id=45860#inline-136211">http://reviews.llvm.org/D16522?id=45860#inline-136211</a>
We can not currently write test cases to investigate this bug further as the
domain generation does not yet handle non-affine-loop regions well.</pre>
