Note that either SCEV or ivopts derives a loop trip count of 1 wrongly out of
the [1] sized array as it is a tail array.  Why this happens in stage2 and not
stage1 is of course a mystery if not (what is probably the case)
tree-scalar-evolution.c, tree-chrec.c or tree-ssa-loop-ivopts.c is miscompiled.
