perf/core improvements and fixes:

Browse source 
User visible:
 
 - Use PERF_RECORD_SWITCH when available in intel-pt, instead of
   "sched:sched_switch" events, enabling an unprivileged user to trace
   multi-threaded or multi-process workloads (Adrian Hunter)
 
 - Always use non inlined file name for 'srcfile' sort key (Andi Kleen)
 
 - Quieten failed to read counter message, helps in systems without
   backend-stalled-cycles (Andi Kleen)
 
 Infrastructure:
 
 - Add a 'perf test' entry for decoding of new x86 instructions (Adrian Hunter)
 
 - Add new instructions (sha, clflushopt, clwb, pcommit, rdpkru, wrpkru, xsavec,
   xsaves, xrstors) to the x86 instruction decoder (Adrian Hunter)
 
 - Add a build test to warn when source code drifts happen for the
   instruction decoder files in the kernel and in tools/perf (Adrian Hunter)
 
 - Copy linux/filter.h to tools/include (He Kuang)
 
 - Support function __get_dynamic_array_len in libtraceevent (He Kuanguuu)
 
 - Tracing path finding/mounting/error reporting refactorings (Jiri Olsa)
 
 - Store CPU socket and core IDs in perf.data (Kan Liang)
 
 - Reorganize add/del probe insertion routines in 'perf probe' (Namhyung Kim, Wang Nan)
