perf/core improvements and fixes: 

objtool:
 
   Josh Poimboeuf:
 
   - Move x86 insn decoder to a common location.
 
   Arnaldo Carvalho de Melo:
 
   - Ignore intentional differences for the x86 insn decoder.
 
 build:
 
   Arnaldo Carvalho de Melo:
 
   - Ignore intentional differences for the x86 insn decoder.
 
 Intel PT:
 
   Josh Poimboeuf:
 
   - Use shared x86 insn decoder.
 
 metric groups:
 
   Jin Yao:
 
   - Scale the metric result.
 
   - Support multiple events.
 
 perf c2c:
 
   Jiri Olsa:
 
   - Display proper cpu count in nodes column.
 
 Miscellaneous:
 
   Kyle Meyer:
 
   - Replace MAX_NR_CPUS with perf_env::nr_cpus_online, i.e. with
     the number of online CPUs as detected at tool start and/or
     recorded in the perf.data file.
 
 libtraceevent:
 
   Tzvetomir Stoyanov:
 
   - Simplify the tep_print_event_* APIs.
 
   - Remove tep_register_trace_clock().
 
   - Change users plugin directory.
 
 Cleanups:
 
   Arnaldo Carvalho de Melo:
 
   - Continue taming the includes hell: remove needless include directives, fix
     the fallout, rinse, repeat.
