13166 (build_type_attribute_qual_variant): When building an attribute
13167 variant, its canonical type is the non-attribute variant. However,
13168 if the attributes are target-dependent and they differ, we need to
13169 use structural equality checks for this type.
13170 (build_qualified_type): A qualified type is not equivalent to its
13171 unqualified variant; set the canonical type appropriately.
13172 (build_distinct_type_copy): When building a distinct type from
13173 another type, the new type is its own canonical type.
13174 (build_variant_type_copy): When building a new type variant, we
13175 assume that it is equivalent to the original type.
13176 (build_pointer_type_for_mode): When building a pointer type, also
13177 build a canonical type pointer.
13178 (build_reference_type_for_mode): When building a reference type,
13179 also build a canonical type reference.
13180 (build_index_type): When we can't hash an index type (e.g.,
13181 because its maximum value is negative), the index type requires
13182 structural equality tests.
13183 (build_array_type): Build the canonical form of an array type.
13184 (build_function_type): Function types require structural equality,
13185 because they contain default arguments, attributes, etc.
13186 (build_method_type_directly): Ditto for method types.
13187 (build_offset_type): Build the canonical offset type.
