Merge branch 'feature/cmake-allow-more-generation-dependencies' into 'master'

ref:dominic/dune-perftool I have the use case of a boundary condition file,
whose changes should retrigger the code generation process.

Merge branch 'feature/use-different-dof-numbers-for-cg' into 'master'

ref:dominic/dune-perftool I'm not 100% sure this gives the right number of
dofs for parallel applications, but at least for serial applications it is
correct.

Merge branch 'feature/sum-factorization-gmsh-files' into 'master'

ref:dominic/dune-perftool On unstructured grids we need to make sure that the
quadrature points on intersections on neighboring cells are visited in the
same order. This is done using edge consistent grids and by constructing the
geometry mappings in the right way.

Still missing:

-   Vectorization
-   Make UG grids edge consistent without writing and reading a gmsh file

I have the use case of a boundary condition file, whose changes should retrigger

Needed in dune-perftool-playground for Navier stokes

There seems to still be some problem.

Merge branch 'feature/fix-constraints-assembly-bug' into 'master'

We previously used bool() on the constraints expression to find out whether we
need to use the DIrichletConstraintsAssembler. However, UFL does the stupid
thing of evaulating

`bool(eq(x[0], 0))`

to False, because x[0] and 0 are obvioulsy not the same. Veeeery bad behaviour
for a symbolic language.

This is done by throwing an exception in the 3D case and doing the 2D case in
the catch part.

Merge branch 'feature/costmodel-validation' into 'master'

The MR adds a new vectorization strategy target, which tries to find a
vectorization strategy whose cost (according to the model strategy) is as
close as possible to a given target. This allows to run several executables
and plot the cost model value against performance data. The actual plotting
work is done in dune-perftool-paperplots. The feature is very niche, and I
tried to minimize the occurence of code paths only necessary for this, but I
think the outcome is quite okay.
