One more argument pro option 3 is the following - we can now write
something like

const VectorXf x = A.solve(b);

It's not a big thing but I am trying hard to use const as often as possible..

So, in case we can use the objects returned by solve-methods as any
other MatrixBase object, I totally prefer option 3.
