       The OpenCL C programming language implements these functions that provide asynchronous copies between
       global and local memory and a prefetch from global memory.

       Perform an async copy of num_gentypes elements from src to dst. The async copy is performed by all
       work-items in a work-group and this built-in function must therefore be encountered by all work-items in
       a work-group executing the kernel with the same argument values; otherwise the results are undefined.

       Returns an event object that can be used by wait_group_events(3clc) to wait for the async copy to finish.
       The event argument can also be used to associate the async_work_group_copy with a previous async copy
       allowing an event to be shared by multiple async copies; otherwise event should be zero.

       If event argument is non-zero, the event object supplied in event argument will be returned.

       This function does not perform any implicit synchronization of source data such as using a barrier(3clc)
       before performing the copy.
