        * cp-tree.h (cxx_int_tree_map): New struct.
        (struct language_function): Add extern_decl_map field.
        * name-lookup.c (pushdecl_maybe_friend): Add x -> t mapping
        to cp_function_chain->extern_decl_map hash table instead of
        copying over DECL_UID.
        * cp-gimplify.c (cxx_int_tree_map_eq, cxx_int_tree_map_hash): New
        functions.
        (cp_genericize_r): Remap DECL_EXTERN local decls using
        cp_function_chain->extern_decl_map hash table.
        * decl.c (finish_function): Clear extern_decl_map.
