According to OpenCL spec:
"To use event objects that refer to commands enqueued in a command-queue as
event objects to wait on by commands enqueued in a different command-queue,
the application must call a clFlush or any blocking commands that perform an
implicit flush of the command-queue where the commands that refer to these
event objects are enqueued."
This patch adds a piQueueFlush function that's lowered to clFinish in OpenCL
and called whenever an unsubmitted cross-queue dependency is about to be used.
