18201 (build_type_attribute_qual_variant): When building an attribute
18202 variant, its canonical type is the non-attribute variant. However,
18203 if the attributes are target-dependent and they differ, we need to
18204 use structural equality checks for this type.
18205 (build_qualified_type): A qualified type is not equivalent to its
18206 unqualified variant; set the canonical type appropriately.
18207 (build_distinct_type_copy): When building a distinct type from
18208 another type, the new type is its own canonical type.
18209 (build_variant_type_copy): When building a new type variant, we
18210 assume that it is equivalent to the original type.
18211 (build_pointer_type_for_mode): When building a pointer type, also
18212 build a canonical type pointer.
18213 (build_reference_type_for_mode): When building a reference type,
18214 also build a canonical type reference.
18215 (build_index_type): When we can't hash an index type (e.g.,
18216 because its maximum value is negative), the index type requires
18217 structural equality tests.
18218 (build_array_type): Build the canonical form of an array type.
18219 (build_function_type): Function types require structural equality,
18220 because they contain default arguments, attributes, etc.
18221 (build_method_type_directly): Ditto for method types.
18222 (build_offset_type): Build the canonical offset type.
