6636 if the attributes are target-dependent and they differ, we need to
6637 use structural equality checks for this type.
6638 (build_qualified_type): A qualified type is not equivalent to its
6639 unqualified variant; set the canonical type appropriately.
6640 (build_distinct_type_copy): When building a distinct type from
6641 another type, the new type is its own canonical type.
6642 (build_variant_type_copy): When building a new type variant, we
6643 assume that it is equivalent to the original type.
6644 (build_pointer_type_for_mode): When building a pointer type, also
6645 build a canonical type pointer.
6646 (build_reference_type_for_mode): When building a reference type,
6647 also build a canonical type reference.
6648 (build_index_type): When we can't hash an index type (e.g.,
6649 because its maximum value is negative), the index type requires
6650 structural equality tests.
6651 (build_array_type): Build the canonical form of an array type.
6652 (build_function_type): Function types require structural equality,
6653 because they contain default arguments, attributes, etc.
6654 (build_method_type_directly): Ditto for method types.
6655 (build_offset_type): Build the canonical offset type.
6656 (build_complex_type): Build the canonical vector type.
