fix the quadruple precision stuff

Browse Source 
this also fixes the SuperLU backend with __float128 on Dune 2.4. The
problem is that due to some hacks within dune-istl, the AMG solver
can't be used because it calls the direct solver directly without an
option to disable this. (This could be fixed in a similar fashion as
the SuperLU backend by copying everything into data structures which
use 'double' before calling into ISTL, but this is a thing for another
time.)
