This testcase doesn't get vectorized anymore, after my patch from
http://gcc.gnu.org/ml/gcc-patches/2005-05/msg02817.html:
"pr21859.f90:6: note: not vectorized: redundant loop. no profit to vectorize.
pr21859.f90:1: note: vectorized 0 loops in function."
so it also doesn't ICE anymore. It might be that it's just avoiding the
problem, but I also can't reproduce PR21831, which is a duplicate of this one,
and which was not affected by my patch, so it might be that something else
fixed the problem (don't know what).
