1833 (build_index_type): When we can't hash an index type (e.g.,
1834 because its maximum value is negative), the index type requires
1835 structural equality tests.
1836 (build_array_type): Build the canonical form of an array type.
1837 (build_function_type): Function types require structural equality,
1838 because they contain default arguments, attributes, etc.
