Intel PT uses the time members from the perf_event_mmap_page to convert between TSC and perf time. Due to a lack of foresight when Intel PT was implemented, those time members were recorded in the (implementation dependent) AUXTRACE_INFO event, the structure of which is generally inaccessible outside of the Intel PT decoder. However now the conversion between TSC and perf time is needed when processing a jitdump file when Intel PT has been used for tracing. So add a user event to record the time members. 'perf record' will synthesize the event if the information is available. And session processing will put a copy of the event on the session so that tools like 'perf inject' can easily access it.
