2971 when we need structural checks.

2981 to represent the size of an array in a template, we need to mark

3004 equality checks, the template class needs structural equality
3006 (tsubst): When reducing the level of a template template
3007 parameter, we require structural equality tests for the resulting
3008 parameter because its template parameters have not had their types
3009 canonicalized. When reducing a template type parameter, find the
3010 canonical reduced type parameter.
