Subject[PATCH 20/20] perf report: Add --percent-type option
Date
Set annotation percent type from following choices:
global-period, local-period, global-hits, local-hits

With following report option setup the percent type will be
passed to annotation browser:

$ perf report --percent-type period-local

The local/global keywords set if the percentage is computed
in the scope of the function (local) or the whole data (global).
The period/hits keywords set the base the percentage is computed
on - the samples period or the number of samples (hits).
