23675 * c-common.c (c_common_nodes_and_builtins): Since variants of
23676 void_type_node get built before it is given a name, we need to
23677 give those variants the name, too.

23683 * stor-layout.c (layout_type): When we don't know the
23684 alignment of a type for which we're building an array, we end up
23685 guessing wrong, so make the type require structural equality.
23686 * tree.c (make_node_stat): When we build a new type, it is its
23687 own canonical type.
23688 (build_type_attribute_qual_variant): When building an attribute
23689 variant, its canonical type is the non-attribute variant. However,
23690 if the attributes are target-dependent and they differ, we need to
23691 use structural equality checks for this type.
23692 (build_qualified_type): A qualified type is not equivalent to its
23693 unqualified variant; set the canonical type appropriately.
23694 (build_distinct_type_copy): When building a distinct type from
23695 another type, the new type is its own canonical type.
23696 (build_variant_type_copy): When building a new type variant, we
23697 assume that it is equivalent to the original type.
23698 (build_pointer_type_for_mode): When building a pointer type, also
23699 build a canonical type pointer.
23700 (build_reference_type_for_mode): When building a reference type,
23701 also build a canonical type reference.
23702 (build_index_type): When we can't hash an index type (e.g.,
23703 because its maximum value is negative), the index type requires
23704 structural equality tests.
23705 (build_array_type): Build the canonical form of an array type.
23706 (build_function_type): Function types require structural equality,
23707 because they contain default arguments, attributes, etc.
23708 (build_method_type_directly): Ditto for method types.
23709 (build_offset_type): Build the canonical offset type.
