13393         (complete_array_type): We need to work with the canonical main

13402         own canonical type.
13403         (build_type_attribute_qual_variant): When building an attribute
13404         variant, its canonical type is the non-attribute variant. However,

13417         (build_index_type): When we can't hash an index type (e.g.,
13418         because its maximum value is negative), the index type requires
13419         structural equality tests.
13420         (build_array_type): Build the canonical form of an array type.
13421         (build_function_type): Function types require structural equality,
