This adds support to gallium, and also to the state tracker for ARB_texture_gather and also the gather features of ARB_gpu_shader5.
It adds a single CAP for the ARB_texture_gather max components query, then another CAP to denote the GPU is capable of SM5 gather. This doesn't add native support for textureGatherOffsets yet, I don't have hw that can do this, so instead I just moved the i965 glsl lowering pass to a generic place and reused it. If you have native support for this feature, then you need to add another CAP + modify the state tracker at the appropriate places. I can help with it, if you are sure your hw can do it. You'd also need to modify the TG4 instruction under the new CAP to accept 4 offsets. I have r600g patches on top of this to add support to r600g, r600/700 can only do ARB_texture_gather, whereas evergreen->cayman can do the SM5 stuff, but not native tGOs.
