    openmp: ensure variables in offload table are streamed out (PRs 94848 + 95551)
    
    gcc/ChangeLog:
    
            * omp-offload.c (add_decls_addresses_to_decl_constructor,
            omp_finish_file): With in_lto_p, stream out all offload-table
            items even if the symtab_node does not exist.
    
    (cherry picked from commit bf4ab2689bb586971d5b2ab6b13d078cd7ac45af)
