The test against cl_khr_create_command_queue extension. It validates if devices with Opencl 1.X can use clCreateCommandQueueWithPropertiesKHR function.
Based on device capabilities test will create queue with NULL properties, CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property and
CL_QUEUE_PROFILING_ENABLE property. Finally simple kernel will be executed on such queue.
