When a defined object is an array with a vector subscript, and it has a finalizable type, it may have a final subroutine with a matching or assumed rank dummy argument that cannot be called. Unless there is also a suitable elemental final subroutine, diagnose such a case with an error message. Differential Revision: https://reviews.llvm.org/D140131
