29937 give those variants the name, too.

29943 * stor-layout.c (layout_type): When we don't know the
29944 alignment of a type for which we're building an array, we end up
29945 guessing wrong, so make the type require structural equality.

29947 own canonical type.
29948 (build_type_attribute_qual_variant): When building an attribute
29949 variant, its canonical type is the non-attribute variant. However,
29950 if the attributes are target-dependent and they differ, we need to
29951 use structural equality checks for this type.
29952 (build_qualified_type): A qualified type is not equivalent to its
29953 unqualified variant; set the canonical type appropriately.
29954 (build_distinct_type_copy): When building a distinct type from
29955 another type, the new type is its own canonical type.
29956 (build_variant_type_copy): When building a new type variant, we
29957 assume that it is equivalent to the original type.
29958 (build_pointer_type_for_mode): When building a pointer type, also
29959 build a canonical type pointer.
29960 (build_reference_type_for_mode): When building a reference type,
29961 also build a canonical type reference.
29962 (build_index_type): When we can't hash an index type (e.g.,
29963 because its maximum value is negative), the index type requires
29964 structural equality tests.
29965 (build_array_type): Build the canonical form of an array type.
29966 (build_function_type): Function types require structural equality,
29967 because they contain default arguments, attributes, etc.
