29027 * stor-layout.c (layout_type): When we don't know the
29028 alignment of a type for which we're building an array, we end up
29029 guessing wrong, so make the type require structural equality.

29031 own canonical type.
29032 (build_type_attribute_qual_variant): When building an attribute
29033 variant, its canonical type is the non-attribute variant. However,
29034 if the attributes are target-dependent and they differ, we need to
29035 use structural equality checks for this type.
29036 (build_qualified_type): A qualified type is not equivalent to its
29037 unqualified variant; set the canonical type appropriately.
29038 (build_distinct_type_copy): When building a distinct type from
29039 another type, the new type is its own canonical type.
29040 (build_variant_type_copy): When building a new type variant, we
29041 assume that it is equivalent to the original type.
29042 (build_pointer_type_for_mode): When building a pointer type, also
29043 build a canonical type pointer.
29044 (build_reference_type_for_mode): When building a reference type,
29045 also build a canonical type reference.
29046 (build_index_type): When we can't hash an index type (e.g.,
29047 because its maximum value is negative), the index type requires
29048 structural equality tests.
29049 (build_array_type): Build the canonical form of an array type.
29050 (build_function_type): Function types require structural equality,
29051 because they contain default arguments, attributes, etc.
