Subject: CRC-32 faster than dummy at "many salts"

Jim -

This is curious:

Benchmarking: CRC-32 [32/64]... (8xOMP) DONE
Many salts:     250216K c/s real, 31238K c/s virtual
Only one salt:  26411K c/s real, 3297K c/s virtual

Benchmarking: dummy [N/A]... DONE
Raw:    90828K c/s real, 90828K c/s virtual

(same build, same machine).

I guess this is due to moving the set_key() overhead out of the loop
(even though for dummy it was merely saving passwords to an array).

I guess we'll get a similar "many salts" speed for "dummy" if we
implement support for dummies with salts. ;-)
