2994 when we need structural checks.

3004 to represent the size of an array in a template, we need to mark

3025 type, set the canonical type for our template class to the primary
3026 template type. If any of the template arguments need structural
3027 equality checks, the template class needs structural equality
3029 (tsubst): When reducing the level of a template template
3030 parameter, we require structural equality tests for the resulting
3031 parameter because its template parameters have not had their types
3032 canonicalized. When reducing a template type parameter, find the
3033 canonical reduced type parameter.
