Subject: After a checkpoint (and thus a stats reset), the
 not_idle_fraction/notIdleFraction statistic is really wrong. The
 notIdleFraction statistic isn't updated when the statistics reset, probably
 because the cpu Status information was pulled into the atomic and timing
 cpus. This changeset pulls Status back into the BaseSimpleCPU object. Anyone
 care to comment on the odd naming of the Status instance? It shouldn't just
 be status because that is confusing with Port::Status, but _status seems a
 bit strage too.
