19610 (build_type_attribute_qual_variant): When building an attribute
19611 variant, its canonical type is the non-attribute variant. However,
19612 if the attributes are target-dependent and they differ, we need to
19613 use structural equality checks for this type.
19614 (build_qualified_type): A qualified type is not equivalent to its
19615 unqualified variant; set the canonical type appropriately.
19616 (build_distinct_type_copy): When building a distinct type from
19617 another type, the new type is its own canonical type.
19618 (build_variant_type_copy): When building a new type variant, we
19619 assume that it is equivalent to the original type.

19621 build a canonical type pointer.
19622 (build_reference_type_for_mode): When building a reference type,
19623 also build a canonical type reference.
19624 (build_index_type): When we can't hash an index type (e.g.,
19625 because its maximum value is negative), the index type requires
19626 structural equality tests.
19627 (build_array_type): Build the canonical form of an array type.
19628 (build_function_type): Function types require structural equality,
19629 because they contain default arguments, attributes, etc.
19630 (build_method_type_directly): Ditto for method types.
19631 (build_offset_type): Build the canonical offset type.
