Add implementations of parallelPrefix() in Arrays for Object, int, long, and double arrays.

Specdiff: http://cr.openjdk.java.net/~chegar/8012647/ver.00/specdiff/java/util/Arrays.html Webrev: http://cr.openjdk.java.net/~chegar/8012647/ver.00/webrev/ This work was done over in the lambda forest mainly by Doug Lea, with some small spec updates by myself. Note: Some work still need to be done to clean up the test, but I would like to focus mainly on the API and try to get it finalized first. -Chris. Is the name final? Just curious if other names such as parallelScan have been considered (and discarded).

"Cumulates in parallel each element ...", I guess I would put a comma before and after "in parallel".

Otherwise the API looks good to me.

-Alan.
