        PR middle-end/88663
        * gimple-fold.c (get_range_strlen): Update prototype to no longer
        need the flexp argument.
        (get_range_strlen_tree): Drop flexp argument.  Drop flexp argument
        from calls to get_range_strlen.  Update comments.  Just update
        VAL for an unterminated const char array and let the reset of the
        code handle it normally.  No longer try to set *flexp.  Adjust
        return value.
        (get_range_strlen): Update for the new get_range_strlen API.
        (get_maxval_strlen): Similarly.
        (gimple_fold_builtin_strlen): Handle update meaning of return value
        from get_range_strlen.
        * gimple-ssa-sprintf.c (get_string_length): Update for the new
        get_range_strlen API.
