Just verified that current trunk is not yet able to vectorize the test.f90
code,
it would be cool if this could be fixed (maybe along the lines of Richard's
previous patch?) as this is similar to CP2K's kernel routines:

I think that scalar code vectorization should instead catch this.

Finding a benchmark could really help to push these items to the top of
vectorizer's todo list.
we're lucky here ;-)
