With @jsalvatier I identified a speed-up in the implementation of NUTS where the energy E0 was recomputed unnecessarily (#1020). This PR moves that computation outside of the inner loop which gave a significant 1.5x speedup in my limited experiments (would be helpful if someone tries this on their own setup).
