The "auxtrace_info" and "auxtrace" functions are not set in "tool" member of
"annotate". As a result, perf annotate does not support parsing itrace data.

A simple example is as follows:

   # perf record -e arm_spe_0/branch_filter=1/ -a sleep 1
   [ perf record: Woken up 9 times to write data ]
   [ perf record: Captured and wrote 20.874 MB perf.data ]
   # perf annotate --stdio
   Error:
   The perf.data data has no samples!

Solution:
1.Add itrace options in help,
2.Set hook functions of "auxtrace_info" and "auxtrace" in perf_tool.
