      StringBuilder.insert is missing a fast-path for the most frequent case when its argument is String.

      Previously they did similar optimization for StringBuilder.append(CharSequence, int, int),
      see https://bugs.openjdk.java.net/browse/JDK-8224986

      The proponent would like to contribute a trivial patch that brings improvement for the case when SB's content is Latin1 and inserted String is Latin1 as well.
