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.

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.

We do this from multiple subdirs

Merge branch 'feature/guard-grid-analysis' into 'master'

consistent-grid-orientation is merely a suggestion. dune-perftool should
perfectly build in its absence.
