i965/gen7: Enable the features required for GL_ARB_sample_shading
- Enable GEN7_WM_MSDISPMODE_PERSAMPLE, GEN7_WM_POSOFFSET_SAMPLE,
GEN7_WM_OMASK_TO_RENDER_TARGET as per extension's specification.
- Only enable one of GEN7_WM_8_DISPATCH_ENABLE or GEN7_WM_16_DISPATCH_ENABLE
when GEN7_WM_MSDISPMODE_PERSAMPLE is enabled. Refer IVB PRM Vol. 2, Part 1,
Page 288 for details.
V2:
- Use shared function _mesa_get_min_invocations_per_fragment().
- Use brw_wm_prog_data variables: uses_pos_offset, uses_omask.
V3:
- Enable simd16 dispatch with per sample shading.
- Make changes to give preference to 'simd16 only' mode over
'simd8 only' mode in case of non 1x per sample shading.
