* cgraphbuild.c (record_reference): Use cgraph_mark_address_taken_node.

	* cgraph.c (cgraph_mark_address_taken_node): New function.
	(dump_cgraph_node): Dump new flag.
	* cgraph.h (struct cgraph_node): Add address_taken.
	(cgraph_mark_address_taken_node): New function.
	* cp/decl2.c (cxx_callgraph_analyze_expr): Use
	cgraph_mark_address_taken.
	* ipa.c (cgraph_postorder): Prioritize functions with address taken
	since new direct calls can be born.
