Subject: NVIDIA GTX 970 (Maxwell 2 / GM204) opencl benchmarks

Sayantan said that GTX 970 benchmarks might be useful for john-dev, so
here are opencl-specific benchmarks for the EVGA model 04G-P4-0972-KR,
non-overclocked.  I wrote a quick wrapper to only run --test for the
the *-opencl formats; I can post full results or other results if
needed.

The test system's current CPU (Sempron 145, sorry) is woefully
underpowered for any CPU-fed formats.  A better chip is on its way,
and I can test again if needed.  The JtR build is from a Sep 27
download bleeding-jumbo; I can run a different version if needed.
NVIDIA drivers are 343.22.
