i965 Gen4/5: Introduce 'interpolation map' alongside the VUE map
The interpolation map (in brw->interpolation_mode) is a new auxiliary structure alongside the post-GS VUE map, which describes the interpolation modes for each VUE slot, for use by the clip and SF stages. This patch introduces a new state atom to compute the interpolation map, and adjusts the program keys for the clip and SF stages, but it is not actually used yet. [V1-2]: Signed-off-by: Olivier Galibert <galibert at pobox.com> V3: Updated for vue_map changes, intel -> brw merge, etc. (Chris Forbes) V4: Compute interpolation map as a new state atom rather than tacking it on the front of the clip setup V5: Rework commit message, make interpolation_mode_map a struct.
