33437 guessing wrong, so make the type require structural equality.
33438 * tree.c (make_node_stat): When we build a new type, it is its
33439 own canonical type.
33440 (build_type_attribute_qual_variant): When building an attribute
33441 variant, its canonical type is the non-attribute variant. However,
33442 if the attributes are target-dependent and they differ, we need to
33443 use structural equality checks for this type.
33444 (build_qualified_type): A qualified type is not equivalent to its
33445 unqualified variant; set the canonical type appropriately.
33446 (build_distinct_type_copy): When building a distinct type from
33447 another type, the new type is its own canonical type.
33448 (build_variant_type_copy): When building a new type variant, we
33449 assume that it is equivalent to the original type.
33450 (build_pointer_type_for_mode): When building a pointer type, also
33451 build a canonical type pointer.
33452 (build_reference_type_for_mode): When building a reference type,
33453 also build a canonical type reference.
33454 (build_index_type): When we can't hash an index type (e.g.,
33455 because its maximum value is negative), the index type requires
33456 structural equality tests.
33457 (build_array_type): Build the canonical form of an array type.
33458 (build_function_type): Function types require structural equality,
33459 because they contain default arguments, attributes, etc.
33460 (build_method_type_directly): Ditto for method types.
33461 (build_offset_type): Build the canonical offset type.
