The two lines that just have () are only supported on i965, nvc0, and
radeonsi.  It's not really that clear.

  GL_ARB_gpu_shader5                                   DONE (i965)
  - 'precise' qualifier                                DONE
  - Dynamically uniform sampler array indices          DONE (r600, softpipe)
  - Dynamically uniform UBO array indices              DONE (r600)
  - Implicit signed -> unsigned conversions            DONE
  - Fused multiply-add                                 DONE ()
  - Packing/bitfield/conversion functions              DONE (r600, softpipe)
  - Enhanced textureGather                             DONE (r600, softpipe)
  - Geometry shader instancing                         DONE (r600, llvmpipe, softpipe)
  - Geometry shader multiple streams                   DONE ()
  - Enhanced per-sample shading                        DONE (r600)
  - Interpolation functions                            DONE (r600)
  - New overload resolution rules                      DONE
