Fortran standard 7.3.2.3 point 7 mentions that a diassociated pointer dynamic type is its declared type. in 9.7.2 note 1, when a NULLIFY statement is applied to a polymorphic pointer, its dynamic type becomes the same as its declared type. This patch enforce these standard points by calling the runtime function `PointerNullifyDerived` with the declared type descriptor.
