Verbose

Benchdnn provides execution information depending on verbosity level. The level setting is controlled by the -vN or --verbose=N option. The higher the level, the more information is provided. Each subsequent level appends new information in addition to the previous level to be printed. Currently, the following information is printed for certain verbosity levels.
