For non-explicit group, perf report has already supported a option
'--group' which can enable group output.
This patch-set will support perf annotate with the same '--group'.
For example,
perf record -e cycles,branches ./div
perf annotate main --stdio --group
: Disassembly of section .text:
:
: 00000000004004b0 <main>:
: main():
:
: return i;
: }
:
: int main(void)
: {
0.00 0.00 : 4004b0: push %rbx
: int i;
: int flag;
: volatile double x = 1212121212, y =
121212;
:
: s_randseed = time(0);
0.00 0.00 : 4004b1: xor %edi,%edi
: srand(s_randseed);
0.00 0.00 : 4004b3: mov $0x77359400,%ebx
:
: return i;
: }

v4:
---
Change function name from perf_evlist_forced_leader to
perf_evlist__force_leader
Impact:
-------
perf evlist: Create new function perf_evlist__force_leader
perf report: Use perf_evlist__force_leader to support '--group'
perf annotate: Support '--group' option
v3:
---------
Move the comment which was on setup_forced_leader() to the

Arnaldo points out that it should be done the way it is for
perf report --group. v2 refers to this way and the patch is
totally rewritten.
