[benchmark] Measure setUpFunction
[benchmark] Measure setUpFunction

Measure the duration of the `setUpFunction` and report it in verbose mode.

This will be used by `BenchmarkDoctor`, to ensure there isn’t unreasonably big imbalance between the time it takes to set up and run the actual benchmark.
