Enabling gles3.1 on gen8 generated a CTS regression:

/tmp/build_root/m64/bin/cts/glcts
--deqp-case=ES2-CTS.gtf.GL2FixedTests.buffer_objects.buffer_objects
dEQP Core GL-CTS-2.0 (0x0052484b) starting..
  target implementation = 'intel-gbm'

Test case 'ES2-CTS.gtf.GL2FixedTests.buffer_objects.buffer_objects'..
#+ Error when binding not generated buffer
#+ Error testing genBuffers
  Fail (Fail)

DONE!

  Failed:        1/1 (100.00%)

    i965/screen: Allow OpenGLES 3.1 for gen8+

    OpenGLES 3.1 cannot be enabled for gen 7 (Ivy Bridge, Haswell) since
    they are still missing ARB_stencil_texturing.
