mhz - calulate processor clock rate
calculates the processor clock rate and megahertz. It uses an
unrolled, interlocked loop of adds or shifts. So far, superscalarness has been
defeated on the tested processors (SuperSPARC, RIOS, Alpha).
Output format is either just the clock rate as a float (-c) or more verbose
39.80 Mhz, 25 nanosec clock
is described more completely in ``mhz: Anatomy of a microbenchmark''
in Proceedings of 1998 USENIX Annual Technical Conference , June 1998.
