perf/core improvements and fixes:

User visible:
 
 - Add branch stack / basic block info to 'perf annotate --stdio', where for
   each branch, we add an asm comment after the instruction with information on
   how often it was taken and predicted. See example with color output at:
 
     http://vger.kernel.org/~acme/perf/annotate_basic_blocks.png
 
   (Peter Zijlstra)
 
 - Only open an evsel in CPUs in its cpu map, fixing some use cases in
   systems with multiple PMUs with different CPU maps (Mark Rutland)
 
 - Fix handling of huge TLB maps, recognizing it as anonymous (Wang Nan)
 
 Infrastructure:
 
 - Remove the symbol filtering code, i.e. the callbacks passed to all functions
   that could end up loading a DSO symtab, simplifying the code, eventually
   allowing what we should have had since day one: removing the 'map' parameter
   from dso__load() functions (Arnaldo Carvalho de Melo)
 
 Arch specific build fixes:
 
 - Fix detached tarball build on powerpc, where we were still accessing a
   file outside tools/ (Ravi Bangoria)
