The main patches are from Christoph. Unfortunately they're a little beyond my understanding of all the vertex-related details, but they generally seemed fine. I'm just going to push these unless someone steps up to review them.

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
