> I find some trivial (and obviously irrelevant) changes to UTF8 validation
> code may cause big variances to benchmark result.
> UTF8 validation functions are inlined and called directly in benchmark. The
> compiler may try to optimize them together with the benchmark loop.
> Un-inline the benchmark-ed functions makes the result predictable and
> explainable.
