1055         own canonical type.
1056         (build_type_attribute_qual_variant): When building an attribute
1057         variant, its canonical type is the non-attribute variant. However,

1071         because its maximum value is negative), the index type requires
1072         structural equality tests.
1073         (build_array_type): Build the canonical form of an array type.
1074         (build_function_type): Function types require structural equality,
