benchmark_harness's `measureFor` returns in microseconds, but we currently show the numbers with the unit "ns". Convert the microseconds reported by benchmark_harness to nanoseconds when reporting. We could also report in microseconds, but the numbers would be very small, with a few zeros before fractional digits. So keep reporting in nanoseconds.
