perf/core improvements and fixes: 

- Support syscall name glob matching in 'perf trace' (Arnaldo Carvalho de Melo)
 
   e.g.:
 
    # perf trace -e pkey_*
    32.784 (0.006 ms): pkey/16018 pkey_alloc(init_val: DISABLE_WRITE) = -1 EINVAL Invalid argument
    32.795 (0.004 ms): pkey/16018 pkey_mprotect(start: 0x7f380d0a6000, len: 4096, prot: READ|WRITE, pkey: -1) = 0
    32.801 (0.002 ms): pkey/16018 pkey_free(pkey: -1                ) = -1 EINVAL Invalid argument
    ^C#
 
 - Do not auto merge counts for explicitely specified events in
   'perf stat' (Arnaldo Carvalho de Melo)
 
 - Fix syntax in documentation of .perfconfig intel-pt option (Jack Henschel)
 
 - Calculate the average cycles of iterations for loops detected by the
   branch history support in 'perf report' (Jin Yao)
 
 - Support PERF_SAMPLE_PHYS_ADDR as a sort key "phys_daddr" in the 'script', 'mem',
   'top' and 'report'. Also add a test entry for it in 'perf test' (Kan Liang)
 
 - Fix 'Object code reading' 'perf test' entry in PowerPC (Ravi Bangoria)
 
 - Remove some duplicate Power9 duplicate vendor events (described in JSON
   files) (Sukadev Bhattiprolu)
 
 - Add help entry in the TUI annotate browser about cycling thru hottest
   instructions with TAB/shift+TAB (Arnaldo Carvalho de Melo)
