Bug detailed description:
-----------------------------
It randomly fails on haswell/ivybridge with mesa 9.1 branch.It fails 2 in 10 runs.
It passes 20 in 20 runs on master branch.

output:
texture-integer: failure with format GL_RGB8I_EXT:
  texture color = 80, 123, 33, 0
  expected color = 0.25, 0.5, 0.75, 0
  result color = 0.25098, 0.501961, 0.74902, 1
PIGLIT: {'result': 'fail' }

Reproduce steps:
----------------------------
1. xinit
2. ./bin/gl-3.0-texture-integer -auto -fbo

This has been fixed in in branch origin/9.1 (which the bug has been filed on), I've confirmed this using branch on IVB and running:

for (( c=1; c<=100; c++ )) do bin/gl-3.0-texture-integer -auto -fbo; done

it passes all of the runs (same on today's Mesa master).
