Timer/counter adjustment by the ->Threads() could use a verification

[LebedevRI]

This could be nothing, but the adjustment

benchmark/src/benchmark_runner.cc

Lines 223 to 225 in 99d1356

	// Adjust real/manual time stats since they were reported per thread.
	i.results.real_time_used /= b.threads;
	i.results.manual_time_used /= b.threads;

and

benchmark/src/reporter.cc

Lines 83 to 93 in 99d1356

	double BenchmarkReporter::Run::GetAdjustedRealTime() const {
	double new_time = real_accumulated_time * GetTimeUnitMultiplier(time_unit);
	if (iterations != 0) new_time /= static_cast<double>(iterations);
	return new_time;
	}
	double BenchmarkReporter::Run::GetAdjustedCPUTime() const {
	double new_time = cpu_accumulated_time * GetTimeUnitMultiplier(time_unit);
	if (iterations != 0) new_time /= static_cast<double>(iterations);
	return new_time;
	}

looks weird. I'm not sure if that is fully correct?
Don't we end up double-correcting the results, since we don't divide the iteration count by thread num,
and thus we basically divide by thread num twice?

As per IRC: The divisor there has been moved around a fair bit, and manual timing was introduced later, so it's entirely possible that we've gotten away from where we need to be here.

I would appreciate a write-up of what should happen in every case that we can review, and then implement (from scratch) and document.
