Relative timing (if benchmark is a relative one). Refer to the
definition of benchmarkModule below for what constitutes a
relative benchmark. For relative benchmarks, relative is
1.0 if the benchmark has the same speed as its baseline,
2.0 is the benchmark is twice as fast, and 0.5 if the
benchmark has half the speed. For non-relative benchmarks, relative is set to NaN, which is testable with std.math.isNaN.
