Benchmarking The Current Intel OpenCL NEO Driver Compute Performance On Ubuntu 19.04

The former Intel open-source OpenCL "Beignet" driver remains available too, for which we took it for a fun round of benchmarking comparison for seeing how these Intel OpenCL Linux drivers currently compete to just running on the CPU via POCL.
