[Mesa-dev] [PATCH 1/2] i965: Enable ES 3.2 sample shading extensions.

This enables:
- GL_OES_sample_shading
- GL_OES_sample_variables
- GL_OES_shader_multisample_interpolation

We pass all the CTS tests, and all but 8 of the dEQP-GLES31 tests.
Half of the failing dEQP tests appear to be broken tests; the other
four still need investigating but cover an obscure corner case.

Otherwise, the functionality is in great shape, and actually in better
shape than the ARB_sample_shading support we've shipped for years
(we fixed a number of bugs when enabling this).  So it makes sense to
enable it for our users in the Mesa 12.0 release.
