14065 variant, its canonical type is the non-attribute variant. However,
14066 if the attributes are target-dependent and they differ, we need to
14067 use structural equality checks for this type.
14068 (build_qualified_type): A qualified type is not equivalent to its

14076 (build_reference_type_for_mode): When building a reference type,
14077 also build a canonical type reference.
14078 (build_index_type): When we can't hash an index type (e.g.,
14079 because its maximum value is negative), the index type requires
14080 structural equality tests.
14081 (build_array_type): Build the canonical form of an array type.
14082 (build_function_type): Function types require structural equality,
14083 because they contain default arguments, attributes, etc.
14084 (build_method_type_directly): Ditto for method types.
