RFR: 8015522 - CharSequence.codePoints can be faster

[Sergey Kuksenko]

Hi
JavaDoc to the method says: "If the sequence is mutated while the stream 
is being read, the result is undefined."

What about exceptions? If the sequence is mutated and length becomes 
smaller you'll get IndexOutOfBoundsException in forEachRemaining method.
