report MPKI instead of hit-rate


MPKI (or misses per 1000 instructions) is better
for comparing CPUs, as hit-rate somewhat 
meaningless (different CPUs make different
amount of requests to the same cache-line).

Also changed the —affinity option to take the
CPU number instead of a big|little string
