perf annotate: Print the evsel name in the stdio output
So that when showing multiple events annotations, we can figure out
which is which:
# perf record -a -e instructions,cycles sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.826 MB perf.data (~36078 samples) ]
# perf evlist
instructions
cycles
# perf annotate intel_idle 2> /dev/null | head -1
Percent | Source code & Disassembly of vmlinux for instructions
