12773 guessing wrong, so make the type require structural equality.
12774 * tree.c (make_node_stat): When we build a new type, it is its
12775 own canonical type.
12776 (build_type_attribute_qual_variant): When building an attribute
12777 variant, its canonical type is the non-attribute variant. However,
12778 if the attributes are target-dependent and they differ, we need to
12779 use structural equality checks for this type.
12780 (build_qualified_type): A qualified type is not equivalent to its
12781 unqualified variant; set the canonical type appropriately.
12782 (build_distinct_type_copy): When building a distinct type from
12783 another type, the new type is its own canonical type.
12784 (build_variant_type_copy): When building a new type variant, we
12785 assume that it is equivalent to the original type.
12786 (build_pointer_type_for_mode): When building a pointer type, also
12787 build a canonical type pointer.
12788 (build_reference_type_for_mode): When building a reference type,
12789 also build a canonical type reference.
12790 (build_index_type): When we can't hash an index type (e.g.,
12791 because its maximum value is negative), the index type requires
12792 structural equality tests.
12793 (build_array_type): Build the canonical form of an array type.
12794 (build_function_type): Function types require structural equality,
12795 because they contain default arguments, attributes, etc.
12796 (build_method_type_directly): Ditto for method types.
12797 (build_offset_type): Build the canonical offset type.
12798 (build_complex_type): Build the canonical vector type.
