	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.
