13721 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
13722 (_cpp_lex_direct): Use linemap_position_for_column.
13723 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
13724 parameter. Instead get it from the line_table global. Adjust callers.
13725 (print): Remove map field. Replace line field to src_line.
