Subject: [PATCH v1 4/9] perf util: Update and print per-thread shadow stats
The functions perf_stat__update_shadow_stats() and
perf_stat__print_shadow_statss() are called to update
and print the shadow stats on a set of static variables.
But the static variables are the limitations to support
per-thread shadow stats.
This patch lets the perf_stat__update_shadow_stats() support
to update the shadow stats on a input parameter 'stat' and
uses update_runtime_stat() to update the stats. It will not
directly update the static variables as before.
And this patch also lets the perf_stat__print_shadow_stats()
support to print the shadow stats from a input parameter 'stat'.
It will not directly get value from static variable. Instead, it now
uses runtime_stat_avg() and runtime_stat_n() to get and compute the
values.
