Log:

        * cgraph.h (struct varpool_node): Add aux.
        * varasm.c (find_decl_and_mark_needed): Force output of varpool nodes.
        * varpool.c (varpool_remove_node): Do not remove initializer.
        (varpool_reset_queue): Export.
        (varpool_finalize_decl): Volatile vars are forced to be output.
        * lto-symtab.c (lto_varpool_replace_node): Clear out initializer of
        replaced decl.
        * ipa.c (enqueue_cgraph_node, enqueue_varpool_node,
        process_references, varpool_can_remove_if_no_refs): New functions.
        (cgraph_remove_unreachable_nodes): Handle variables too.

At r159319, the assembly generated for anon6.s was...

        .const
        .align 2
__ZN12_GLOBAL__N_11BIiE1cE:
        .space 4
        .constructor

...while at r159321, the assembly becomes...
