Account for StringBuilder#toString as a separate builder state.

Otherwise, as demonstrated at b/147718617, a dominant state that has
conditional path with append() and another conditional path with
toString() could be regarded as a state with a single call chain,
resulting in incorrect compile-time optimization of builder.
