[PATCH 04/15] perf tools: Add map_groups to 'struct addr_location'

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

From: Arnaldo Carvalho de Melo <acme@redhat.com>

From there we can get al->mg->machine, so replace that field with the
more useful 'struct map_groups' that for now we're obtaining from
al->map->groups, and that is one thing getting into the way of maps
being fully shareable.
