[PATCH 23/27] perf tools: Add processor socket info to hist_entry and addr_location

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@xxxxxxxxx>

This information will come from perf.data files of from the current
system, cached when needed, such as when the 'socket' sort order gets
introduced.
