16917 * print-tree.c (print_node): Display canonical type information
16919 * stor-layout.c (layout_type): When we don't know the
16920 alignment of a type for which we're building an array, we end up
16921 guessing wrong, so make the type require structural equality.
16922 * tree.c (make_node_stat): When we build a new type, it is its
16923 own canonical type.
16924 (build_type_attribute_qual_variant): When building an attribute
16925 variant, its canonical type is the non-attribute variant. However,
16926 if the attributes are target-dependent and they differ, we need to
16927 use structural equality checks for this type.
16928 (build_qualified_type): A qualified type is not equivalent to its
16929 unqualified variant; set the canonical type appropriately.
16930 (build_distinct_type_copy): When building a distinct type from
16931 another type, the new type is its own canonical type.
16932 (build_variant_type_copy): When building a new type variant, we
16933 assume that it is equivalent to the original type.
16934 (build_pointer_type_for_mode): When building a pointer type, also
16935 build a canonical type pointer.
16936 (build_reference_type_for_mode): When building a reference type,
16937 also build a canonical type reference.
16938 (build_index_type): When we can't hash an index type (e.g.,
16939 because its maximum value is negative), the index type requires
16940 structural equality tests.
16941 (build_array_type): Build the canonical form of an array type.
16942 (build_function_type): Function types require structural equality,
16943 because they contain default arguments, attributes, etc.
16944 (build_method_type_directly): Ditto for method types.
