Moving 'struct perf_counts' and associated functions into separate object, so we could remove stat.c object dependency from python build. It makes the python code to build properly, because it fails to load due to missing stat-shadow.c object dependency if some patches from Kan Liang are applied. So apply this one, then Kan's.
