Log:

	* cgraph.c (cgraph_node::make_local): No name is unique during
	incremental linking.
	* cgraph.h (can_be_discarded_p): Update comment; also common and
	WEAK in named sections can be discarded; when doing incremental
	link do not rely on resolution being the final one.
	* varasm.c (default_binds_local_p_3, decl_binds_to_current_def_p):
	When symbol can be discarded, do not rely on resolution info.
	* symtab.c (symtab_node::nonzero_address): Take into account that
	symbol can be discarded.
	* ipa-visibility.c (update_visibility_by_resolution_info): Handle
	definition correctly.
	(function_and_variable_visibility): Do not set unique_name when
	incrementally linking.
