[Bug fortran/37427] New: Passed-object dummy argument should be polymorphic

["domob at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

As polymorphic entities are not implemented in gfortran, the handling of
passed-object dummy arguments allows (or requires) them to be declared
non-polymorphic (TYPE(t)) while they should in fact be CLASS(t):

MODULE m

  TYPE :: t
  CONTAINS
    PROCEDURE :: proc
  END TYPE t

CONTAINS

  SUBROUTINE proc (me)
    TYPE(t) :: me ! should be CLASS(t) :: me
  END SUBROUTINE proc

END MODULE m
