        Represent column numbers using line-map's source_location.
        The "next available source_location" is now managed internally by
        line-maps.c rather than by clients.
        * line-map.h (struct line_map):  New field column_bits.
        <from_line>:  Rename field to start_location.
        (struct line_maps):  New fields highest_location and max_column_hint.

        * cpphash.h (struct cpp_reader) <map>:  Field removed.  Because
        linemap_position_for_column may unpredictably change the current map,
        it is cleaner and simpler for us to not cache it in cpp_reader.
        (struct cpp_buffer):  New sysp field.

        (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.
        * cpplex.c (_cpp_process_line_notes, _cpp_lex_direct,
        _cpp_skip_block_comment):  Use CPP_INCREMENT_LINE.
        (_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.

        * 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.
