r600g: Implement gpu_shader5 textureGather
Adds 0-3 textureGather component selection and non-constant offsets Caveat: 0 and 1 texture swizzles only work if textureGather component select is 3 or a component that does not exist in the sampler texture format. This is a hardware limitation, any other value returns 128/255=0.501961 for both 0 and 1. Passes all textureGather piglit tests on radeon 6670, except for those using 0/1 texture swizzles due to aforementioned reason.
