tree.c (free_lang_data_in_type): Do not clear fields dependent on debuginfo level setting. 

2011-12-14  Richard Guenther  <rguenther@suse.de>

	* tree.c (free_lang_data_in_type): Do not clear fields
	dependent on debuginfo level setting.
	(find_decls_types_r): Use TYPE_STUB_DECL rathern than TREE_CHAIN.
	* tree.h (TYPE_STUB_DECL): Properly check that we access
	a type.
