In D144997, the dynamic type of polymorphic entities is reset to the declared type when the FROM is deallocated. To do this, the declared type was passed as a fir.type_desc op. For unlimited polymorphic entities, this should just be a null pointer. Reviewed By: PeteSteinfeld Differential Revision: https://reviews.llvm.org/D145380
