tree.c (make_vector_type): Do not set TYPE_DEBUG_REPRESENTATION_TYPE.

2010-09-10  Richard Guenther  <rguenther@suse.de>

	* tree.c (make_vector_type): Do not set TYPE_DEBUG_REPRESENTATION_TYPE.
	* tree.h (TYPE_DEBUG_REPRESENTATION_TYPE): Remove.
	* lto-streamer-out.c (lto_output_ts_type_tree_pointers): Do
	not stream TYPE_DEBUG_REPRESENTATION_TYPE.
	* lto-streamer-in.c (lto_input_ts_type_tree_pointers): Likewise.
