perf list: Support long jevents descriptions
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]
