as far as i can evaluate this without deeper insight into tess, this
patchseries looks good to me!

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.
