[Mesa-dev] [PATCH 04/12] spirv: Add SubgroupBallotKHR capability to SubgroupSize and SubgroupLocalInvocationId

From: Ian Romanick <ian.d.romanick at intel.com>

The SPV_KHR_shader_ballot spec says:

    (Add the SubgroupBallotKHR capability to SubgroupSize.)

    (Add the SubgroupBallotKHR capability to SubgroupLocalInvocationId.)

Yet the annotations are missing from the JSON.  See also
