Description
Summary:
Add testing for higher order autodiff. We need to be able to determine where we aren't able to compile models in higher order.
This goes along with stan-dev/math#403.
Description:
We can determine which functions aren't compiling with higher-order autodiff through the language pretty easily. We've included a lot of instantiations of functions through src/test/test-models/good/*.stan functions.
I'm planning on running through them all and testing that forward mode and mixed mode compiles.
Reproducible Steps:
We don't have an easy way of reproducing it.
Current Version:
v2.13.0

Research direction
Start by reviewing the function instantiations under src/test/test-models/good/*.stan and the related stan-dev/math#403 issue. Run through the available models with forward-mode and mixed-mode higher-order autodiff compilation, documenting which functions compile and which do not.
