perf/core improvements and fixes: 

perf annotate:
 
 - Allow showing offsets in more than just jump targets, use the new
   'O' hotkey in the TUI, config ~/.perfconfig annotate.offset_level
   for it and for --stdio2 (Arnaldo Carvalho de Melo)
 
 - Use the resolved variable names from objdump disassembled lines to
   make them more compact, just like was already done for some instructions,
   like "mov", this eventually will be done more generally, but lets now add
   some more to the existing mechanism (Arnaldo Carvalho de Melo)
 
 perf record:
 
 - Change warning for missing topology sysfs entry to debug, as not all
   architectures have those files, s390 being one of those (Thomas Richter)
 
 perf sched:
 
 - Fix -g/--call-graph documentation (Takuya Yamamoto)
 
 perf stat:
 
 - Enable 1ms interval for printing event counters values in (Alexey Budankov)
 
 perf test:
 
 - Run dwarf unwind  on arm32 (Kim Phillips)
 
 - Remove unused ptrace.h include from LLVM test, sidesteping older
   clang's lack of support for some asm constructs (Arnaldo Carvalho de Melo)
 
 perf version:
 
 - Do not print info about HAVE_LIBAUDIT_SUPPORT in 'perf version --build-options'
   when HAVE_SYSCALL_TABLE_SUPPORT is true, as libaudit won't be used in that
   case, print info about syscall_table support instead (Jin Yao)
 
 Build system:
 
 - Use HAVE_..._SUPPORT used consistently (Jin Yao)
 
 - Restore READ_ONCE() C++ compatibility in tools/include (Mark Rutland)
 
 - Give hints about package names needed to build jvmti (Arnaldo Carvalho de Melo)
