perf tools: Add support for PERF_RECORD_ITRACE_START
Add support for the PERF_RECORD_ITRACE_START event type. This event can
be used to determine the pid and tid that are running when Instruction
Tracing starts. Generally that information would come from a
sched_switch event but, at the start, no sched_switch events may yet
have been recorded.
