Add A New OpenCL Test

• Create source file src/opencl_<name>.cpp.
• Add a bench file benchmarking/opencl_<name>.bench.
• Register the test in CMakeLists.txt with cl_test(<name> 300).
• Use the cl_check() function to test OpenCL call return values. Put it on a separate line after the OpenCL call. Do not wrap the OpenCL call.
• Build with 'make -j6'
• Run from build directory without GPU: ./opencl_<name> -v --cpu.
• Run from build directory with GPU: ./opencl_<name> -v --gpu.
• Fix any errors shown in the output from the above runs.

Minimal src/opencl_<name>.cpp:

#include "opencl_common.h"

int main(int argc, char** argv)
{
    opencl_req_t reqs{}; // Set reqs.usage and reqs.cmdopt for cmd line options
    opencl_setup_t cl = cl_test_init(argc, argv, "opencl_<name>", reqs);
    bench_start_iteration(cl.bench);
    // ... do work here ...
    bench_stop_iteration(cl.bench);
    cl_test_done(cl);
    return 0;
}

Minimal benchmarking/opencl_<name>.bench:

{ "name": "opencl_<name>", "description": "<short description of test>" }
