    Fortran: avoid NULL pointer dereferences

    CLASS(), PARAMETER is not yet properly implemented in gfortran.  Using it
    in declarations could lead to subsequent NULL pointer dereferences during
    checking or simplification of expressions involving those CLASS variables.

    gcc/fortran/ChangeLog:

            PR fortran/103137
            PR fortran/103138
            * check.c (gfc_check_shape): Avoid NULL pointer dereference on
            missing ref.
            * simplify.c (gfc_simplify_cshift): Avoid NULL pointer dereference
            when shape not set.
            (gfc_simplify_transpose): Likewise.
