Subject: [PATCH 01/20] perf hists: Add struct hists pointer to struct hist_entry

From: Jiri Olsa <jolsa@...hat.com>

Adding pointer back to the parent struct hists for struct hists_entry.

This will be useful in future for any hist_entry's data computation,
that depends on total data of its parent hists.
