Since ppc64le implies Power 8 as a minimum, it makes sense that the same features are included. Since the pwr8 processor model will likely be getting new features until the implementation is complete, I created a new list to add these updates to. This will include them in both pwr8 and ppc64le.
Furthermore, it seems that it would make sense to compose the feature lists for other processor models (pwr3 and up). I would be more than happy to make this change if everyone agrees.
