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outdated comment on DECL_RTL_SET_P check.
