Subject: [PATCH 13/26] perf sort: Provide a way to find out if per-thread bucketing is in place

From: Namhyung Kim <namhyung@...nel.org>

Now the UI browsers will be able to offer thread related operations only
if the thread is part of the sort order in use, i.e. if hist_entry stats
are all for a single thread.
