Please Review: 6984084 (str) n times repetition of character constructor for java.lang.String

[Jim Gish]

Please review 
http://cr.openjdk.java.net/~jgish/6984084-jdk8-StringRepeat/ 
<http://cr.openjdk.java.net/%7Ejgish/6984084-jdk8-StringRepeat/>

This started in lambda, making changes to both StringJoiner and String.  
However, the dependence of String.repeat() on StringJoiner has been 
removed and the resulting non-lambda classes moved here for review.  
There will be a separate change and review for the StringJoiner changes 
in lamda-dev.

Thanks,
    Jim
