    [runtime] Fix flattening of ConsStrings with empty first parts. · c7762231
    Andreas Haas authored
    String::SlowFlatten assumed that ConsStrings with empty first parts have
    flattened strings as their second part. TurboFan, however, can create
    ConsStrings with empty first parts and arbitrary second parts. With
    this CL we call String::Flatten on the second part of a ConsString if
    the first part is empty, but only when String::Flatten would not call
    String::SlowFlatten.
