perf annotate stdio2: Print more descriptive event information header
To match the recently added event header information to --tui, e.g.:
# perf annotate --ignore-vmlinux --stdio2 _raw_spin_lock_irqsave
Samples: 128 of event 'cycles:ppp', 4000 Hz, Event count (approx.): 48617682
_raw_spin_lock_irqsave() /proc/kcore
0.78 nop
7.03 push %rbx
3.12 pushfq
6.25 pop %rax
nop
mov %rax,%rbx
3.12 cli
nop
xor %eax,%eax
mov $0x1,%edx
79.69 lock cmpxchg %edx,(%rdi)
test %eax,%eax
↓ jne 2b
mov %rbx,%rax
pop %rbx
← retq
2b: mov %eax,%esi
→ callq *ffffffffb30eaed0
mov %rbx,%rax
pop %rbx
← retq
