Subject: OpenCL tests on HD 7970

magnum, Lukas, Sayantan, Samuele -

Here's a full set of OpenCL tests for magnum-jumbo on my 7970.
(I ran these one by one because we do not yet have "format destructors"
and because a segfault or the like would prevent further tests.)

Raw:    75590 c/s real, 186407 c/s virtual

(This is pretty good speed.  hashcat is reported to do 132.1k c/s on
5970, which is slightly faster.  I'd expect something like 100k for 7970.)
