* cgraph.c (dump_cgraph_node): Print new flags.

	(dump_cgraph_varpool_node): Likewise.
	(decide_variable_is_needed): Initialize externally_visible flag.
	* cgraph.h (cgraph_local_info): Add externally_visible flag.
	(cgraph_varpool_node): Likewise.
	(cgraph_function_flags_ready): Declare.
	* cgraph.c (cgraph_mark_local_functions): Rename to ...
	(cgraph_function_and_variable_visibility) ... this one; handle
	externally_visible flags.
	(decide_is_function_needed): Set externally_visible flag.
	(cgraph_finalize_function): Deal properly with early cleanups.
	(cgraph_optimize): Update call of
	cgraph_function_and_variable_visibility.
