Merge more of the uflacsrepresentation code into ffc.
Set test.py to use unoptimized quadrature mode by default when running with uflacs, easier to compare what the code does.
Merge branch 'martinal/topic-merge-more-into-uflacsrepr' into martinal/topic-move-more-into-uflacsrepr
Add base class ufc::integral with function enabled_coefficients()
returning a vector<bool> with which form coefficients are used
by this particular integral. Currently returns all true in a hacky
implementation to test in dolfin before generating code from ffc.
Add code generation for enabled_coefficients. Assumes data from ufl IntegralData.
Update reference data pointer to 778ebaa7d3ede5cc46b81b8d13a4931d9b891b8e.
Bugfix in *_integral_implementation after addition of new function.
