Bug detailed description:
-----------------------------
It fails on i965 platforms with mesa master branch, works well on 10.5 branch.
Following cases also fail with the same bisect commit:
Piglit:
glean_fragprog1-z-write_test
glean_fragprog1-rsq_test_2_(reciprocal_square_root_of_negative_value)
Ogles3conform(fails on SNB+):
ES3-CTS.shaders.struct.uniform.sampler_array_fragment
Bisect shows: d47405eb707b9921f70454049677a9d504ee3fa6 is the first bad commit.
