    fortran: Fix finalizer list truncated when >= 3 finalizers match [PR121972]

    When gfc_resolve_finalizers copies matching finalizers from the template
    type into a derived type's finalizer list, a linked-list bug caused the
    third and later entries to be orphaned.  Fix by using the standard
    tail-pointer idiom.

            PR fortran/121972

    gcc/fortran/ChangeLog:

            * resolve.cc (gfc_resolve_finalizers): Fix linked-list tail-pointer
            bug that dropped all but the first two finalizers from a derived
            type's finalizer list when three or more matched.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/pdt_70.f03: Add a matrix finalizer and update the
            check of the value of 'flag'.
