For HMC sampling correctness, we only need to test against one AD backend, but we currently test against a few.
We only need to test gradient evaluation for the AD functionality test, but we currently run HMC, which is an overkill.

A counter point to this: TuringLang/DynamicPPL.jl#612
Sometimes AD only breaks when we're sampling 😬
