From: Andi Kleen <ak@linux.intel.com>
Previously we were dropping the useful longer descriptions that some
events have in the event list completely. This patch makes them appear with
perf list.
Old perf list:
baclears:
baclears.all
[Counts the number of baclears]
vs new:
perf list -v:
...
baclears:
baclears.all
[The BACLEARS event counts the number of times the front end is resteered, mainly when
the Branch Prediction Unit cannot provide a correct prediction and this is corrected
by the Branch Address Calculator at the front end. The BACLEARS.ANY event counts the
number of baclears for any type of branch]

Add support to group the output of perf list by the Topic field
in the JSON file.
Example output:
% perf list
...
Cache:
l1d.replacement
[L1D data line replacements]
l1d_pend_miss.pending
[L1D miss oustandings duration in cycles]
l1d_pend_miss.pending_cycles
[Cycles with L1D load Misses outstanding]
l2_l1d_wb_rqsts.all
[Not rejected writebacks from L1D to L2 cache lines in any state]
l2_l1d_wb_rqsts.hit_e
[Not rejected writebacks from L1D to L2 cache lines in E state]
l2_l1d_wb_rqsts.hit_m
[Not rejected writebacks from L1D to L2 cache lines in M state]
...
Pipeline:
arith.fpu_div
[Divide operations executed]
arith.fpu_div_active
[Cycles when divider is busy executing divide operations]
baclears.any
[Counts the total number when the front end is resteered, mainly when the BPU cannot provide a correct prediction and this is corrected by
other branch handling mechanisms at the front end]
br_inst_exec.all_branches
[Speculative and retired branches]
br_inst_exec.all_conditional
[Speculative and retired macro-conditional branches]
br_inst_exec.all_direct_jmp
[Speculative and retired macro-unconditional branches excluding calls and indirects]
br_inst_exec.all_direct_near_call
[Speculative and retired direct near calls]
br_inst_exec.all_indirect_jump_non_call_ret
