Subject[PATCH 18/18] perf report: Add report.cumulate config option
Date
From: Namhyung Kim <namhyung.kim@lge.com>

Add report.cumulate config option for setting default value of
callchain accumulation. It affects the report output only if
perf.data contains callchain info.

A user can write .perfconfig file like below to enable accumulation
by default:

$ cat ~/.perfconfig
[report]
cumulate = true

And it can be disabled through command line:

$ perf report --no-cumulate
