7580 (build_index_type): When we can't hash an index type (e.g.,
7581 because its maximum value is negative), the index type requires
7582 structural equality tests.
7583 (build_array_type): Build the canonical form of an array type.
7584 (build_function_type): Function types require structural equality,
7585 because they contain default arguments, attributes, etc.

7587 (build_offset_type): Build the canonical offset type.
