2233 (build_type_attribute_qual_variant): When building an attribute
2234 variant, its canonical type is the non-attribute variant. However,

2246 also build a canonical type reference.
2247 (build_index_type): When we can't hash an index type (e.g.,
2248 because its maximum value is negative), the index type requires
2249 structural equality tests.
2250 (build_array_type): Build the canonical form of an array type.
2251 (build_function_type): Function types require structural equality,
2252 because they contain default arguments, attributes, etc.

2254 (build_offset_type): Build the canonical offset type.
