Have sparse LU return permutation matrices rather than sparse matrices.
This could well impact user code. It'd be interesting to see if there
is any actual fall-out... Quite often, the permutation matrices are
applied to *dense* vectors. Returning permutation matrices rather
than sparse matrices is a slight performance enhancement, but likely
lost in the noise.
