9383 also build a canonical type reference.
9384 (build_index_type): When we can't hash an index type (e.g.,
9385 because its maximum value is negative), the index type requires
9386 structural equality tests.
9387 (build_array_type): Build the canonical form of an array type.
9388 (build_function_type): Function types require structural equality,
9389 because they contain default arguments, attributes, etc.

9391 (build_offset_type): Build the canonical offset type.
9392 (build_complex_type): Build the canonical vector type.
