6753 (build_index_type): When we can't hash an index type (e.g.,
6754 because its maximum value is negative), the index type requires
6755 structural equality tests.
6756 (build_array_type): Build the canonical form of an array type.
6757 (build_function_type): Function types require structural equality,
6758 because they contain default arguments, attributes, etc.
