Kan Liang 9e207ddfa2 perf report: Show call graph from reference events ...

Introduce --show-ref-call-graph for perf report to print reference
callgraph for no callgraph event.

Here is an example.

 perf report --show-ref-call-graph --stdio

 # To display the perf.data header info, please use
 --header/--header-only options.

 #
 # Total Lost Samples: 0
 #
 # Samples: 5  of event 'cpu/cpu-cycles,call-graph=fp/'
 # Event count (approx.): 144985

 # Children      Self  Command  Shared Object     Symbol
 # ........  ........  .......  ................  ........................................
