    Add newline when checking path profitability.
    
    It looks like we're missing a newline for cases where we don't print
    anything.
    
    gcc/ChangeLog:
    
            * tree-ssa-threadbackward.cc (possibly_profitable_path_p): Always
            add newline.
            (profitable_path_p): Same.
