[PATCH 06/21] perf report: Cache cumulative callchains

It is possble that a callchain has cycles or recursive calls. In that case it'll end up having entries more than 100% overhead in the output. In order to prevent such entries, cache each callchain node and skip if same entry already cumulated. Tested-by: Arun Sharma Acked-by: Jiri Olsa Cc: Fre
