32608 (build_type_attribute_qual_variant): When building an attribute
32609 variant, its canonical type is the non-attribute variant. However,
32610 if the attributes are target-dependent and they differ, we need to
32611 use structural equality checks for this type.
32612 (build_qualified_type): A qualified type is not equivalent to its
32613 unqualified variant; set the canonical type appropriately.
32614 (build_distinct_type_copy): When building a distinct type from
32615 another type, the new type is its own canonical type.
32616 (build_variant_type_copy): When building a new type variant, we
32617 assume that it is equivalent to the original type.
32618 (build_pointer_type_for_mode): When building a pointer type, also
32619 build a canonical type pointer.
32620 (build_reference_type_for_mode): When building a reference type,
32621 also build a canonical type reference.
32622 (build_index_type): When we can't hash an index type (e.g.,
32623 because its maximum value is negative), the index type requires
32624 structural equality tests.
32625 (build_array_type): Build the canonical form of an array type.
32626 (build_function_type): Function types require structural equality,
32627 because they contain default arguments, attributes, etc.
32628 (build_method_type_directly): Ditto for method types.
32629 (build_offset_type): Build the canonical offset type.
