12010 also build a canonical type reference.
12011 (build_index_type): When we can't hash an index type (e.g.,
12012 because its maximum value is negative), the index type requires
12013 structural equality tests.
12014 (build_array_type): Build the canonical form of an array type.

12016 because they contain default arguments, attributes, etc.
