    * lto-cgraph.c (compute_ltrans_boundary): When alias is in the boundary,
    add its target too.
    * lto.c (add_references_to_partition): Add also aliased nodes.
    (add_cgraph_node_to_partition,
    add_varpool_node_to_partition): Work on nodes, not functions/variables;
    when adding alias, add also the aliased object.

    * gcc.dg/lto/pr52634_1.c: New testcase.
    * gcc.dg/lto/pr52634_0.c: New testcase.
