[PATCH V6 07/17] perf tools: Add Intel PT decoder
Add support for decoding an Intel Processor Trace.
Intel PT trace data must be 'decoded' which involves walking
the object code and matching the trace data packets.
The decoder requests a buffer of binary data via a get_trace()
call-back, which it decodes using instruction information which
it gets via another call-back walk_insn().
