softpipe: start adding gather support (v2)
This adds both ARB_texture_gather and the enhanced gather
for ARB_gpu_shader5.
This passes all the piglit tests, it relies on the GLSL
lowering pass to make textureGatherOffsets work.
v2: use inline to get gather component (Brian)
fix function name, add asserts (Brian)
