Andi Kleen 44d49a6002 perf stat: Support metrics in --per-core/socket mode 
Enable metrics printing in --per-core / --per-socket mode. We need to
save the shadow metrics in a unique place. Always use the first CPU in
the aggregation. Then use the same CPU to retrieve the shadow value
later.

Example output:

  % perf stat --per-core -a ./BC1s
