Bug detailed description:
---------------------------
It fails on i965 with mesa master branch, works well on 10.4 branch.
Following cases also fail with the same bisect commit:
ES2-CTS.gtf.GL.mix.mix_float_vert_xvary_yconsthalf_aconsthalf
ES2-CTS.gtf.GL.mix.mix_vec2_vert_xvary_yconsthalf_aconsthalf
ES2-CTS.gtf.GL.sin.sin_float_vert_xvary
Bisect shows: 44573458bdc52acc304fb75d6df502312b8e149c is the first bad commit
