Jiri Olsa 749230b06a tracing, function_graph: Add context-info support for function_graph tracer 
The function_graph tracer does not follow global context-info option.
Adding TRACE_ITER_CONTEXT_INFO trace_flags check to enable it.

With following commands:
	# echo function_graph > ./current_tracer
	# echo 0 > options/context-info
	# cat trace

This is what it looked like before:
# tracer: function_graph
#
#     TIME        CPU  DURATION                  FUNCTION CALLS
#      |          |     |   |                     |   |   |   |
 1)   0.079 us    |          } /* __vma_link_rb */
 1)   0.056 us    |          copy_page_range();
 1)               |          security_vm_enough_memory() {
...

This is what it looks like now:
# tracer: function_graph
#
  } /* update_ts_time_stats */
  timekeeping_max_deferment();
...
