Since different ARCHs (even different generations in the same ARCH) may use different events. The output also vary on different platforms. For a metricgroup, only outputting the value of each metric is good enough. Add a new field default_metricgroup in evsel to indicate an event of the default metricgroup. For those events, printout() should print the metricgroup name rather than each event. Add perf_stat__skip_metric_event() to skip the evsel in the Default metricgroup, if it's not running or not the metric event. Add print_metricgroup_header_t to pass the functions which print the display name of each metricgroup in the Default metricgroup. Support all three output methods. Factor out perf_stat__print_shadow_stats_metricgroup() to print out each metrics.
