Bug detailed description:
---------------------------
It fails on BSW with mesa master branch, works well on BDW.
Following cases also fail:
spec_EXT_transform_feedback_intervening-read_output_use_gs
spec_EXT_transform_feedback_intervening-read_prims_generated_use_gs
spec_EXT_transform_feedback_intervening-read_prims_written_use_gs
spec_EXT_transform_feedback_overflow-edge-cases_use_gs

output:
Incorrect data for vertex 1.  Expected 1, got 0.Incorrect data for vertex 2.  Expected 2, got 0.Incorrect data for vertex 3.  Expected 3, got 0.Incorrect data for vertex 4.  Expected 4, got 0.Incorrect data for vertex 5.  Expected 5, got 0.Incorrect data for vertex 6.  Expected 6, got 0.Incorrect data for vertex 7.  Expected 7, got 0.Incorrect data for vertex 8.  Expected 8, got 0.Incorrect data for vertex 9.  Expected 9, got 0.PIGLIT: {"result": "fail" }
