12929 (build_index_type): When we can't hash an index type (e.g.,

12931 structural equality tests.
12932 (build_array_type): Build the canonical form of an array type.
12933 (build_function_type): Function types require structural equality,
12934 because they contain default arguments, attributes, etc.
