18360 (build_index_type): When we can't hash an index type (e.g.,
18361 because its maximum value is negative), the index type requires
18362 structural equality tests.
18363 (build_array_type): Build the canonical form of an array type.

18365 because they contain default arguments, attributes, etc.
