Subject: [PATCH v6 06/12] perf tools: drop in cpu_aggr_map struct
Replace usages of perf_cpu_map with cpu_aggr map in
places that are involved with perf stat aggregation.
This will then later be changed to be a map of
cpu_aggr_id rather than an int so that more data can
be stored.
No functional changes.
