	(_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.
