    Fortran: Fix finalization resolution with deep copy
    
    Follow-up patch to
    "Fortran/OpenMP: Support mapping of DT with allocatable components"
    https://gcc.gnu.org/pipermail/gcc-patches/2022-March/591144.html
    
    gcc/fortran/ChangeLog:
    
            * resolve.c (gfc_resolve_finalizers): Also resolve allocatable comps.
    
    gcc/testsuite/ChangeLog:
    
            * gfortran.dg/finalize_38.f90: New test.
