[PATCH 03/10] perf report: Apply --percent-limit to callchains also

[Arnaldo Carvalho de Melo]

See http://www.infradead.org/rpr.html

From: Namhyung Kim <namhyung@xxxxxxxxxx>

Currently --percent-limit option only works for hist entries.  However
it'd be better to have same effect to callchains as well
