6078         (complete_array_type): We need to work with the canonical main

6087         own canonical type.

6103         because its maximum value is negative), the index type requires
6104         structural equality tests.
6105         (build_array_type): Build the canonical form of an array type.
6106         (build_function_type): Function types require structural equality,

6109         (build_offset_type): Build the canonical offset type.
