To analyze the hcalls with perf kvm stat, we need the hcall related tracepoint information to be exported.
This patch adds hcall tracepoints "kvm_hv:kvm_hcall_enter" and "kvm_hv:kvm_hcall_exit" to kvm_perf.h. So, perf will now know to look for these tracepoints if "perf kvm stat record" is invoked to collect guest hcall statistics.
