perf/urgent fixes: 

perf report/top:
 
   Jiri Olsa:
 
   - Fix time sorting for big numbers, i.e.:
 
     perf report -s time -F time,overhead --stdio
 
   was failing because the sort comparision routine was returning 'int' while
   that particular -s key was int64_t, fix it.
 
 perf scripting engines:
 
   Steven Rostedt (VMware):
 
   - Iterate on tep event arrays directly, fixing a bug when generating python/perl
     source code from a perf.data file with more than one tracepoint event.
