After perf_evlist__create_maps() being executed, we can get all
threads from /proc. And via thread_map__nr(), we can also get
the number of threads.

With the number of threads, the patch allocates a buffer which
will record the shadow stats for these threads.

The buffer pointer is saved in stat_config.

why don't you add struct perf_stat_config::*stats|stats_num in this patch?
I dont see any reason it's introduced earlier
