CFL:C0+ changed the status of those registers which are now blacklisted by default.
This is breaking a number of CTS tests on GL & Vulkan :
KHR-GL45.pipeline_statistics_query_tests_ARB.functional_fragment_shader_invocations (GL)
dEQP-VK.query_pool.statistics_query.fragment_shader_invocations.* (Vulkan)
v2: Only use one whitelist entry (Lionel)
