        * toplev.c (process_options): Don't set up default values for
        the sra_max_scalarization_size_{speed,size} parameters.
        * tree-sra (analyze_all_variable_accesses): If no values
        have been set for the sra_max_scalarization_size_{speed,size}
        parameters, call get_move_ratio to get target defaults.
