After recording PEBS-via-PT, perf script will not accept 'iregs' field e.g.
# perf record -c 10000 -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}'
-I -- ls -l
...
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.062 MB perf.data ]
# ./perf script --itrace=eop -F+iregs
Samples for 'dummy:u' event do not have IREGS attribute set. Cannot print
'iregs' field.
Fix by using allow_user_set, which is true when recording AUX area data.
