[PATCH 13/28] perf hists: Sort hist entries by accumulated period

When callchain accumulation is requested, we need to sort the entries by accumulated period value. When accumulated periods of two entries are same (i.e. single path callchain) put the caller above since accumulation tends to put callers on higher position for obvious reason. Cc: Arun Sharma
