Inferno Contribution: flops

This contribution comes from Robert Bohrer and is a floating point benchmark program. He translated the original flops.c program into Limbo as flops.b. The results of several different tests are display as Mflops.

Example output on a 500Mhz AMD K6-2 PC running Inferno hosted under Plan 9 (in compiled mode):
