This test case makes probably only sense with -ftree-optimize one SSE
systems. Assuming that Tobias S.'s patch -ftree-optimize will be checked
in, I left out any dg-options.

When gimple was changed, this broke the sqrt(:) vectorization on AMD64.

As suggested by Thomas:
"could write this into a test case for gfortran.dg? If it broke once, we
should at make sure it doesn't break again."


Of course it broke gcc.dg/vect/no-math-errno-vect-pow-1.c, so we already
noticed (should have at least ;)).
