[Mesa-dev] [PATCH] r600g: atomize sampler state

This generally looks good. I have tested it on R700 and there are 2
regressions. I'll try to take a look at them tomorrow.
1) The test arb_seamless_cubemap is failing. I think the only way to
make that feature work correctly is to add a separate atom for it.
2) spec/glsl-1.30/execution/vs-textureSize-compare.shader_test is
causing this CS checker error:
"[23499.051137] radeon 0000:01:00.0: forbidden register 0x0000a520 at 464"
Maybe some of the offsets are wrong?
One more thing. "dw[7]" in r600_pipe_sampler_state is not very
readable. How about this:
uint32_t tex_sampler_words[3];
uint32_t border_color[4];
