	* cgraph.h (+varpool_can_remove_if_no_refs): Move here from ...;
	when !flag_toplevel_reorder do not remove unless variable is
	COMDAT or ARTIFICIAL.
	* ipa.c (varpool_can_remove_if_no_refs): ... here.
	(cgraph_remove_unreachable_nodes): Only analyzed nodes needs to stay.
	* cgraphunit.c (cgraph_analyze_functions): Dump varpool, too.
	* varpool.c (decide_is_variable_needed): Do not handle visibility issues.
	(varpool_finalize_decl): Likewise.
	(varpool_remove_unreferenced_decls): Use varpool_mark_needed_node; update
	outdated comment on DECL_RTL_SET_P check.
