This adds two independent options for tuning solves.
-amat_type shell: causes Amat and Pmat to be different matrices, with shell
used for Amat. It's technically possible to use other matrix formats
here.
-pmat_pbdiagonal: causes Pmat to be assembled as point-block diagonal.
Note that this usually only makes sense in addition to -amat_type shell
because otherwise your KSP is only working with the point-block diagonal.
