This paper proposes the addition of the asycnhronous work group copy and prefetch builtin functions in SYCL. As these builtin functions require sycnhronization within a SYCL kernel, this paper also proposes the addition of the the device_event class and the wait group events builtin.

The reason for having a `multi_ptr` parameter rather than an `accessor` is so that localy created pointers can also be used as well as pointers passed from the host.

The data type of the `multi_ptr` is `dataT` the data type of the components of the vec class template specialisation. This requires thhat the pointer passed to eiither `load()` or `store()` must match the type of the `vec` instance itself.
