        * vapool.c: Include tree-ssa-alias.h, gimple.h and lto-streamer.h
        (varpool_get_constructor): New function.
        (varpool_ctor_useable_for_folding_p): Break out from ...
        (ctor_for_folding): ... here; use varpool_get_constructor.
        (varpool_assemble_decl): Likewise.
        * lto-streamer.h (struct output_block): Turn cgraph_node
        to symbol filed.
        (lto_input_variable_constructor): Declare.
        * ipa-visibility.c (function_and_variable_visibility): Use
        varpool_get_constructor.
        * cgraph.h (varpool_get_constructor): Declare.
        (varpool_ctor_useable_for_folding_p): New function.
        * lto-streamer-out.c (get_symbol_initial_value): Take encoder
        parameter; return error_mark_node for non-trivial constructors.
        (lto_write_tree_1, DFS_write_tree): UPdate use of
        get_symbol_initial_value.
        (output_function): Update initialization of symbol.
        (output_constructor): New function.
        (copy_function): Rename to ..
        (copy_function_or_variable): ... this one; handle vars too.
        (lto_output): Output variable sections.
        * lto-streamer-in.c (input_constructor): New function.
        (lto_read_body): Rename from ...
        (lto_read_body_or_constructor): ... this one; handle vars
        too.
        (lto_input_variable_constructor): New function.
        * ipa-prop.c (ipa_prop_write_jump_functions,
        ipa_prop_write_all_agg_replacement): Update.
        * lto-cgraph.c (compute_ltrans_boundary): Use it.
        (output_cgraph_opt_summary): Set symbol to NULL.

        * lto-partition.c (add_references_to_partition): Use
        varpool_ctor_useable_for_folding_p.
        * lto.c (lto_read_in_decl_state): Update sanity check.
