This adds support for gl_SampleMaskIn and gl_InvocationID system values to gallium, mesa/st, and nvc0. The relevant piglit tests pass, except 2 gl_InvocationID-related ones that fail due to the linking being delayed by mesa/st (I think). I wrote a lame one for gl_SampleMaskIn that just makes sure that it's == 1 in a non-ms scenario, as nothing better seemed to be available.
None of this functionality is actually available yet since it's all behind ARB_gpu_shader5. However you can test it out by adding MESA_EXTENSION_OVERRIDE=GL_ARB_gpu_shader5 Note that this patchset applies on top of my ARB_sample_shading patch because that one adds the earlier system values.
