Save all stage 1 sum factorization kernels that are used in
accumulation expression in the cache during the dry run. Discard all
inactive sum factorization kernels in decide_vetorization_strategy.

Make anisotropic quadrature order possible for non DG examples.

This did not work previously, since we are patching the submodules, which
makes them dirty, and then `git submodule update` will refuse to update them.

Closes #96.

- Use TensorProductElement in one example.

- We still use the sumfact option to swicth to the sum factorization
  code branch. This way it is still possible to easily swicth between
  sumfact and non sumfact code.

- Only TensorProductElements with the same degree in all directions
  will work. Anisotropie and adaption of quadrature rule will happen
  in the next commits.

These are broken, see !98.

The y ar enot properly implemented right now, do not seem
to be necessary and conflict with recent changes in loopy.

[bugfix] Correctly iterate over children of MixedElement

See merge request !171

The way we currently iterate over children of mxied elements
was plain wrong for nested mixed elements. The tests that
revealed this will soon follow.

So far, we used a global context to tell the normal visitor,
that it is generating for driver code. This was feasible, as
we only had one differing implementation. With more differences,
it is better style to derive from the visitor and implement
the differences there.
