This is enough to enable tessellation support on nvc0. It seems to work a lot better on my GF108 than GK208. I suspect that there's some sort of scheduling shenanigans that need to be adjusted for kepler+. Or perhaps some shader header things.
Even with the GF108, I still get occasional blue triangles in Heaven, but I get a *ton* of them on the GK208 -- seemingly the same issue, but it's much worse on there. Also there's about a 100% chance that gl_PrimitiveID doesn't work. In any case, I plan on pushing this semi-soon unless there are any loud objections. I don't think it's going to do too much good sitting in my tree, or too much evil sitting upstream while core + st/mesa are worked out.
