Subject: [PATCH 07/24] perf evsel: Add hists helper
From: Arnaldo Carvalho de Melo <acme@...hat.com>
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.
