Looks like resume_nontimer_queries/emit_query_begin is recursing into suspend_nontimer_queries/emit_query_end

Was running on HD6850 `OpenGL version string: 3.0 Mesa 10.4.0-devel (git-2adf7ee)' With GALLIUM_HUD="fps,draw-calls;samples-passed+primitives-generated;ia-vertices+ia-primitives;vs-invocations+ps-invocations+hs-invocations+ds-invocations;VRAM-usage+GTT-usage" R600_DEBUG=hyperz. Though, I assume GALLIUM_HUD="fps" could be enough.
