19685 own canonical type.
19686 (build_type_attribute_qual_variant): When building an attribute
19687 variant, its canonical type is the non-attribute variant. However,
19688 if the attributes are target-dependent and they differ, we need to
19689 use structural equality checks for this type.
19690 (build_qualified_type): A qualified type is not equivalent to its
19691 unqualified variant; set the canonical type appropriately.
19692 (build_distinct_type_copy): When building a distinct type from
19693 another type, the new type is its own canonical type.

19698 (build_reference_type_for_mode): When building a reference type,
19699 also build a canonical type reference.
19700 (build_index_type): When we can't hash an index type (e.g.,
19701 because its maximum value is negative), the index type requires
19702 structural equality tests.
19703 (build_array_type): Build the canonical form of an array type.
19704 (build_function_type): Function types require structural equality,
19705 because they contain default arguments, attributes, etc.
19706 (build_method_type_directly): Ditto for method types.
19707 (build_offset_type): Build the canonical offset type.
