Comment(by jhpalmieri):
Without the patch, "solve_right" seems to work for nonsquare matrices over
RDF, I guess because it's using the generic "solve_right" method from
matrix2.pyx. With the patch, it looks like this won't work any more; is
that right? Is there a good reason for not allowing square matrices? We
could instead add a method {{{_solve_right_nonsingular_square}}} to
matrix_double_dense.pyx, and then I think this should be called by the
generic solve_right method.
For "solve_left", could we just remove the version from
matrix_double_dense.pyx altogether, and just use the generic version?
