[PATCH v2 perf,bpf 1/3] perf, bpf: Introduce PERF_RECORD_BPF_EVENT

For better performance analysis of BPF programs, this patch introduces PERF_RECORD_BPF_EVENT, a new perf_event_type that exposes BPF program load/unload information to user space. Each BPF program may contain up to BPF_MAX_SUBPROGS (256) sub programs. The following example shows kernel symbols for
