<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

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.
