[PATCH] Fix PR45789


This fixes PR45789, we don't need types on INDENTIFIER nodes, so just
do not stream them.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Richard.

2010-11-19  Richard Guenther  <rguenther@suse.de>

	PR lto/45789
	* lto-streamer-out.c (lto_output_ts_common_tree_pointers): For
	IDENTIFIERs do not stream TREE_TYPE.
	* lto-streamer-in.c (lto_input_ts_common_tree_pointers): Likewise.
