If it's generally not a problem to do optimizations, we should turn
them on by default. But there have been (and will be again once I get
to it) optimizations for the tensor representation. These are quite
costly to compute, so then it would be sensible to turn them off by
default.

Should there be a default value for optimization which may be
different for different representations?

In any case, a user needs to be able to control the level of
optimization (and representation) easily from DOLFIN.
