Seems in line with nvc0, but I assume you tested this? e.g. the
occlquery mesa demo, or the relevant piglit tests?

Yes. And I added a temporary entry to the Gallium HUD for testing timestamp-disjoint.

PIPE_QUERY_TIMESTAMP_DISJOINT could not work because q->ready was always
set to FALSE. To fix this issue, add more different states for queries
according to nvc0.
