i965: Split brw_set_prim into brw/gen6 variants
The "slight optimization to avoid the GS program" in brw_set_prim() is not used by Gen 6, since Gen 6 doesn't use a GS program. Also, Gen 6 doesn't use reduced primitives. Also, document that intel_context.reduced_primitive is only used for Gen < 6 Reviewed-by: Eric Anholt <[email protected]> Signed-off-by: Chad Versace <[email protected]>
