        (print_location):  If col==0, try SOURCE_COLUMN of line.
        (cpp_error):  Use cur_token's src_loc field, rather than line+col.
        * cpplib.c (do_diagnostic):  Token's src_loc fields replaces line+col.

        (_cpp_temp_token):  Replace cpp_token's line+col fields by src_loc.
        (_cpp_get_fresh_line):  Don't need to adjust line for missing newline.
        (_cpp_lex_direct):  Use linemap_position_for_column.
        * c-ppoutput.c (maybe_print_line, print_line):  Don't take map
        parameter.  Instead get it from the line_table global.  Adjust callers.
        (print):  Remove map field.  Replace line field to src_line.
        (init_pp_output, account_for_newlines, maybe_print_line):  Adjust.
        (cb_line_change):  Use SOURCE_COLUMN.  Minor optimizations.
        (pp_file_change):  Use MAIN_FILE_P since we cannot checked print.map.
        Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include.
        * cpptrad.c (copy_comment):  Rename variable.
        * c-lex.c (map):  Remove static variable, for same reason we removed
        cpp_reader's map field.
        (cb_line_change, cb_def_pragma, cb_define, cb_undef):  Hence we need
        to call linemap_lookup.
        (cb_line_change):  Token's line field replaced by src_loc.
        (fe_file_change):  Use MAINFILE_P and LAST_SOURCE_LINE macros.
        Don't save new_map.

        * cpphash.h, cpperror.c, cpplib.h:  Some renames of fileline to
        source_location.
