IIRC Intel's OpenCL CPU implementation supports out-of-order queues; I 
don't know about their iGPUs. Intel surely knows (they have an OpenCL 
forum).
Take care when testing: AFAIK there is no guarantee that the execution 
order (including parallel execution of commands) is identical across 
runs -> if a test "passes" this may mean extremely little in general.
