OpenCL version is committed now too. Very little tested as of yet. I 
will (probably soon) change it to use a split loop kernel and auto-tune. 
Until then, try manually setting GWS so it ends up 0.2-0.5 of the 
resulting c/s speed. This means each kernel run is 200-500 ms so you 
don't end up hitting a watchdog timer or lose your desktop.

$ GWS=$((128*1024)) OMP_NUM_THREADS=8 ../run/john -dev=0 
-form:zip-opencl -test
Will run 8 OpenMP threads
Device 0: Tahiti
Local worksize (LWS) 64, Global worksize (GWS) 131072
Benchmarking: zip-opencl, ZIP [PBKDF2-SHA1 AES OpenCL]... (8xOMP) DONE
Raw:	278876 c/s real, 164525 c/s virtual
