25316 if the attributes are target-dependent and they differ, we need to
25317 use structural equality checks for this type.
25318 (build_qualified_type): A qualified type is not equivalent to its

25320 (build_distinct_type_copy): When building a distinct type from
25321 another type, the new type is its own canonical type.
25322 (build_variant_type_copy): When building a new type variant, we

25327 also build a canonical type reference.
25328 (build_index_type): When we can't hash an index type (e.g.,
25329 because its maximum value is negative), the index type requires
25330 structural equality tests.
25331 (build_array_type): Build the canonical form of an array type.
25332 (build_function_type): Function types require structural equality,
25333 because they contain default arguments, attributes, etc.
