Additionally we had to change String.equals() so that it recognizes can return "true" for matching instances of String.SubSequence.
I'm not sure about this either, especially with String.equals clearly 
specifying that the argument must be a String.

The updates to AbstractStringBuilder append and insert seems unrelated, 
I assume you did measurements. Just wondering about separating them out 
as a separate patch?
