        <pre>The OpenGL ES 3.0 CTS:
ES3-CTS.shaders.uniform_block.random.nested_structs_arrays.9 fails for BDW with
Mesa 11.0.2 (git-51e0b06).

I have bisected the first problematic commit to:

commit 18e73bf7f8b12022e02db3230ee109657581900b
Author: Connor Abbott <<a href="mailto:cwabbott0@gmail.com">cwabbott0@gmail.com</a>>
Date:   Tue Jun 30 13:38:20 2015 -0700

    i965/fs: remove special case in setup_payload_interference()

    regs_read() will handle LINTERP for us since the previous commit. In
    addition, we were being too conservative, since it will only read 2
    registers on SIMD8.

    instructions in affected programs:     9061 -> 8893 (-1.85%)
    helped:                                10
    HURT:                                  0
    GAINED:                                0
    LOST:                                  0

    All of the changes were due to spills being eliminated, mostly in KSP
    shaders.

With a revert of above commit the test pass. However, the revert cause
regressions for other CTS tests. Also, the commit appear to be part of a
cooperative patch-set from Jordan and Connor.
