[PATCH 03/29] perf hists: Add _idx fields into struct perf_hpp_fmt

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Jiri Olsa <jolsa@kernel.org>

Currently there's no way of comparing hpp format entries, which is
needed in following patches.

Adding _idx fields into struct perf_hpp_fmt to recognize and be able to
compare hpp format entries.
