	* utils2.c (build_allocator): Provide the extra arguments to
	make_aligning_type for super-aligned objects allocated from the default
	pool. Leave enough room for a pointer before the aligning field, and
	store the system's allocator return value there.
	(build_call_alloc_dealloc): When releasing a super-aligned object,
	retrieve the system's allocator return value from where build_allocator
	has stored it, just ahead of the adjusted address we are passed.
	(build_call_raise): Handle properly the generation of line numbers when
	the node is marked No_Location.
	(compare_elmt_bitpos): Use tree_int_cst_compare.  Stabilize the sort
	by using DECL_UID on ties.
	(build_binary_op) <EQ_EXPR>: Accept fat pointer types with the same
	main variant.
	(build_call_raise): Handle converting exception into goto; support new
	argument KIND.
	(build_component_ref): Add new arg to build_call_raise.
