10235 (build_type_attribute_qual_variant): When building an attribute
10236 variant, its canonical type is the non-attribute variant. However,
10237 if the attributes are target-dependent and they differ, we need to
10238 use structural equality checks for this type.
10239 (build_qualified_type): A qualified type is not equivalent to its
10240 unqualified variant; set the canonical type appropriately.
10241 (build_distinct_type_copy): When building a distinct type from
10242 another type, the new type is its own canonical type.
10243 (build_variant_type_copy): When building a new type variant, we

10247 (build_reference_type_for_mode): When building a reference type,
10248 also build a canonical type reference.
10249 (build_index_type): When we can't hash an index type (e.g.,
10250 because its maximum value is negative), the index type requires
10251 structural equality tests.
10252 (build_array_type): Build the canonical form of an array type.
10253 (build_function_type): Function types require structural equality,
10254 because they contain default arguments, attributes, etc.
