Bug detailed description:
-----------------------------
It fails on Ironlake with mesa master branch, and works well on 10.1 branch.
Following cases also fail with same bisect commit:
shaders_glsl-fs-uniform-array-2
shaders_glsl-fs-uniform-array-6
shaders_glsl-fs-uniform-array-7
Bisect shows: b207e88b25e526d0f1ada7b19605b880a27866dc is the first bad commit.

i965/fs: Support pull parameters in SIMD16 mode.
This is just a matter of reusing the pull/push constant information set
up by the SIMD8 compile.
This gains us 78 SIMD16 programs in shader-db.
