        * expr.c : Add a prototype for scalarize_intrinsic_call.
        (gfc_simplify_expr): Use scalarize_intrinsic_call for elemental
        intrinsic function calls.
        (scalarize_intrinsic_call): Add 'init_flag' argument. Check if
        the expression or any of the actual argument expressions are
        NULL. Before calling gfc_check_init_expr, check 'init_flag'.
        Only simplify the scalarized expressions if there are no errors
        on the stack.
        (gfc_check_init_expr): Set 'init_flag' true in the call to
        scalarize_intrinsic_call.
