nv50: shader generation patches
Hi ! I've been trying to improve NV50 shader generation a bit the last couple of weeks, so here is
what I've produced. I don't know if it's usable for you or just a pile of horrible hacks, but at
least it makes some mesa demos render more correcly, p.e. the teapot (aside from mip-mapping issues
of the floor texture), arbfplight, and I think the gears also didn't appear as they
