i965/fs: Fix broken math on values loaded from uniform buffers on gen6.
In a debug build this led to assertion failures, but on a non-debug build the hardware would just reference the whole vec8 instead of the same channel 8 times. Fixes the new piglit glsl-1.40/uniform-buffer/fs-exp2. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=57121 Note: This is a candidate for the stable branches Reviewed-by: Kenneth Graunke <[email protected]>
