24389         (complete_array_type): We need to work with the canonical main

24398         own canonical type.

24413         (build_index_type): When we can't hash an index type (e.g.,
24414         because its maximum value is negative), the index type requires
24415         structural equality tests.
24416         (build_array_type): Build the canonical form of an array type.
24417         (build_function_type): Function types require structural equality,
