12791         (complete_array_type): We need to work with the canonical main

12800         own canonical type.

12815         (build_index_type): When we can't hash an index type (e.g.,
12816         because its maximum value is negative), the index type requires
12817         structural equality tests.
12818         (build_array_type): Build the canonical form of an array type.
12819         (build_function_type): Function types require structural equality,
