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'.
