perf session: Add instruction tracing options
It is assumed that AUX area decoding will synthesize events for
consumption by other tools.
At this time, the main use of AUX area tracing will be to capture
instruction trace (aka processor trace) data.
The nature of instruction tracing suggests the initial inclusion of
options for "instructions" and "branches" events, but more could be
added as needed.
