While working on improvements to the region info analysis, this test case caused
an incorrect region 1 => 2 to be detected. It is incorrect because entry has an
outgoing edge to 3. This is interesting because 1 dom 2 and 2 pdom 1, which
should have been enough to prevent incoming forward edges into the region and
outgoing forward edges from the region.
