[PATCH 07/24] perf evsel: Add hists helper

From: Arnaldo Carvalho de Melo
Date: Tue Oct 14 2014 - 17:10:20 EST

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Not all tools need a hists instance per perf_evsel, so lets pave the way
to remove evsel->hists while leaving a way to access the hists from a
specially allocated evsel, one that comes with space at the end where
lives the evsel.
