perf stat: Define a structure for per-thread shadow stats Perf has a set of static variables to record the runtime shadow metrics stats. While if we want to record the runtime shadow stats for per-thread, it will be the limitation. This patch creates a structure and the next patches will use this structure to update the runtime shadow stats for per-thread.
