If we have matvecmul and vecmul, then how to implement bilinear forms
efficiently becomes pretty clear:
np.vecmul(b, np.matvecmul(A, b))

I'm not sure writing a dedicated function in numpy itself makes sense for
something this easy.

I suppose there would be some performance gains from not saving the
immediate result, but I suspect this would be premature optimization in
most cases.
