i965 Gen4/5: clip: correctly handle flat varyings
Previously we only gave special treatment to the builtin color varyings.
This patch adds support for arbitrary flat-shaded varyings, which is
required for GLSL 1.30.
Based on Olivier Galibert's patch from last year:
http://lists.freedesktop.org/archives/mesa-dev/2012-July/024340.html
V5: Move key.do_flat_shading to brw_clip_compile.has_flat_shading
V6: Real bools.
