i965 Gen4/5: clip: Add support for noperspective varyings
Adds support for interpolating noperspective varyings linearly in screen
space when clipping.
Based on Olivier Galibert's patch from last year:
http://lists.freedesktop.org/archives/mesa-dev/2012-July/024341.html
At this point all -fixed and -vertex interpolation tests work.
V5: Add brw_clip_compile.has_noperspective_shading rather than another
key flag.
V6: Real bools.
