perf report: Add --stats option to display quick data statistics
Add --stats option to display quick data statistics of event numbers,
without any further processing, like the one at the end of the perf
report -D command.
$ perf report --stat
Aggregated stats:
TOTAL events: 4566
MMAP events: 113
LOST events: 19
COMM events: 3
FORK events: 400
SAMPLE events: 3315
MMAP2 events: 32
FINISHED_ROUND events: 681
THREAD_MAP events: 1
CPU_MAP events: 1
TIME_CONV events: 1
I found this useful when hunting lost events for another change.
