    PR lto/48354
    * tree.c (find_decls_types_r): Also walk DECL_ORIGINAL_TYPE.
    * tree-streamer-in.c (lto_input_ts_decl_non_common_tree_pointers):
    Stream DECL_ORIGINAL_TYPE.
    * tree-streamer-out.c (write_ts_decl_non_common_tree_pointers):
    Likewise.

    lto/
    * lto.c (lto_ft_decl_non_common): When we merged DECL_ORIGINAL_TYPE
    with the type of the TYPE_DECL clear DECL_ORIGINAL_TYPE.

    * g++.dg/lto/pr48354-1_0.C: New testcase.
