From: Taeung Song <treeze.tae...@gmail.com> Add --show-nr-samples option to "perf annotate" so that it matches "perf report".
Committer note: Note that it can't be used together with --show-total-period, which seems like a silly limitation, that can be lifted at some point. Made it bail out if not on --stdio.
