OpenCL-Benchmark v1.6

• automatically use zero-copy buffers on CPUs/iGPUs to reduce memory footprint
• bandwidth kernels now write non-zero data, to avoid hardware optimizations for zero-initialized buffers

OpenCL-Benchmark v1.5

• enabled benchmarking FP16 vector arithmetic on Nvidia Pascal and newer GPUs with Nvidia driver 520 or newer
• removed wait() call at the end of the benchmark on Linux
