22829 (build_type_attribute_qual_variant): When building an attribute
22830 variant, its canonical type is the non-attribute variant. However,
22831 if the attributes are target-dependent and they differ, we need to
22832 use structural equality checks for this type.
22833 (build_qualified_type): A qualified type is not equivalent to its
22834 unqualified variant; set the canonical type appropriately.
22835 (build_distinct_type_copy): When building a distinct type from
22836 another type, the new type is its own canonical type.
22837 (build_variant_type_copy): When building a new type variant, we

22841 (build_reference_type_for_mode): When building a reference type,
22842 also build a canonical type reference.
22843 (build_index_type): When we can't hash an index type (e.g.,
22844 because its maximum value is negative), the index type requires
22845 structural equality tests.
22846 (build_array_type): Build the canonical form of an array type.
22847 (build_function_type): Function types require structural equality,
22848 because they contain default arguments, attributes, etc.
22849 (build_method_type_directly): Ditto for method types.
