[PATCH v3 06/11] perf util: Update and print per-thread shadow stats

From: Jin Yao
Date: Tue Nov 28 2017 - 23:11:50 EST

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.
