LGTM, thanks!

Yes, that would also be quite nice.

Generically, I'd like to have features corresponding to the different ISA levels, so that -mattr=+ISA2.06 (bikeshed welcome) turns on all of the corresponding features. Then, for the POWER cores, we can specify their features mostly in terms of the ISA revision they support.
