Log and benchmark the workings of a single block and silence whatever logging that may have happened inside it (unless use_silence is set to false).
The benchmark is only recorded if the current level of the logger matches the log_level, which makes it easy to include benchmarking statements in production software that will remain inexpensive because the benchmark will only be conducted if the log level is low enough.
