Ugly LTO hacks.  To be nuked.

See http://gcc.gnu.org/ml/gcc-patches/2011-03/msg01556.html for details.


Diego.

	* lto-streamer-in.c (lto_input_ts_decl_non_common_tree_pointers):
	Always read DECL_SAVED_TREE.
	* lto-streamer-out.c (lto_output_ts_decl_common_tree_pointers):
	Igonore varpool nodes.
	(lto_output_ts_decl_non_common_tree_pointers): Output NULL
	DECL_SAVED_TREE.
