Test problem for the new form compiler working. The speedup is a factor
10 for assembling Poisson's equation in 3D. Good news is that the code
automatically generated by FFC is just as fast as the hand-optimized code.
There might be other bottlenecks (such as adding the contributions to the
sparse matrix) that affect these numbers.
