Migrating from OpenCL Code to DPC++

In the current version of DPC++, the runtime employs OpenCL code to enact the parallelism. DPC++ typically requires fewer lines of code to implement kernels and also fewer calls to essential API functions and methods. It enables creation of OpenCL programs by embedding the device source code in line with the host source code.
Most of the OpenCL application developers are aware of the somewhat verbose setup code that goes with offloading kernels on devices. Using DPC++, it is possible to develop a clean, modern C++ based application without most of the setup associated with OpenCL C code. This reduces the learning effort and allows for focus on parallelization techniques.
However, OpenCL application features can continue to be used via the SYCL API. The updated code can use as much or as little of the SYCL interface as desired.
