perf annotate: Add itrace options support
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.
Before:
# 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 "id_index", "auxtrace_info" and "auxtrace" in perf_tool.
After:
# perf record --all-user -e arm_spe_0/branch_filter=1/ ls
Couldn't synthesize bpf events.
perf.data
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.010 MB perf.data ]
# perf annotate --stdio
