11156 own canonical type.
11157 (build_type_attribute_qual_variant): When building an attribute
11158 variant, its canonical type is the non-attribute variant. However,
11159 if the attributes are target-dependent and they differ, we need to
11160 use structural equality checks for this type.
11161 (build_qualified_type): A qualified type is not equivalent to its
11162 unqualified variant; set the canonical type appropriately.
11163 (build_distinct_type_copy): When building a distinct type from
11164 another type, the new type is its own canonical type.

11170 also build a canonical type reference.
11171 (build_index_type): When we can't hash an index type (e.g.,
11172 because its maximum value is negative), the index type requires
11173 structural equality tests.
11174 (build_array_type): Build the canonical form of an array type.
11175 (build_function_type): Function types require structural equality,
11176 because they contain default arguments, attributes, etc.
11177 (build_method_type_directly): Ditto for method types.
11178 (build_offset_type): Build the canonical offset type.
