Right now it appears templates like ipopt.c don't use evaluate_partial_derivates_and_objective, meaning that shared sub-expressions get recomputed inbetween calculating the objective / partials. Solution: pass evaluate_partial_derivatives_and_objective for both and use a global flag to check if it's already been computed per iteration?
