draw/softpipe: add clip vertex support. (v2)
softpipe always clipped using the position vector, however for unclipped vertices it stored the position in window coordinates, however when position and clipping are separated, we need to store the clip-space position and the clip-space vertex clip, so we can interpolate both separately. This means we have to take the clip space position and store it to use later. This allows softpipe to pass all the clip-vertex piglit tests. v2: fix llvm draw regression, the structure being passed into llvm needed updating, remove some hardcoded ints that should have been enums while there.
