The test code contains two loops, where the first one is exected to be vectorized. The commit that broke that vectorization was the first of several that enabled vectorization of both loops. Now, that GCC can vectorize the whole function, let's adjust this test to expect vectorization of both loops by ensuring that we don't write to the helper-array 'tmp'.
