	PR c++/33112
	PR c++/33185
	* tree.c (cplus_array_compare): Compare pointers, not types.
	(build_cplus_array_type_1): Store new array type into the hash
	table before building the canonical type; build the canonical type
	correctly.
	(cp_build_qualified_type_real): Put all of the array types with
	cv-qualified element types into the C++ array hash table, built as
	variants of the unqualified versions.
