17802 void_type_node get built before it is given a name, we need to
17803 give those variants the name, too.
17804 (complete_array_type): We need to work with the canonical main
17805 type of the array, from which we will build the qualified version.
17806 * params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
17807 * print-tree.c (print_node): Display canonical type information
17809 * stor-layout.c (layout_type): When we don't know the
17810 alignment of a type for which we're building an array, we end up
17811 guessing wrong, so make the type require structural equality.
17812 * tree.c (make_node_stat): When we build a new type, it is its
17813 own canonical type.
17814 (build_type_attribute_qual_variant): When building an attribute
17815 variant, its canonical type is the non-attribute variant. However,
17816 if the attributes are target-dependent and they differ, we need to
17817 use structural equality checks for this type.
17818 (build_qualified_type): A qualified type is not equivalent to its
17819 unqualified variant; set the canonical type appropriately.
17820 (build_distinct_type_copy): When building a distinct type from
17821 another type, the new type is its own canonical type.
17822 (build_variant_type_copy): When building a new type variant, we
17823 assume that it is equivalent to the original type.
17824 (build_pointer_type_for_mode): When building a pointer type, also
17825 build a canonical type pointer.
17826 (build_reference_type_for_mode): When building a reference type,
17827 also build a canonical type reference.
17828 (build_index_type): When we can't hash an index type (e.g.,
17829 because its maximum value is negative), the index type requires
17830 structural equality tests.
17831 (build_array_type): Build the canonical form of an array type.
17832 (build_function_type): Function types require structural equality,
17833 because they contain default arguments, attributes, etc.
17834 (build_method_type_directly): Ditto for method types.
17835 (build_offset_type): Build the canonical offset type.
