RFR of JDK 8168505: Remove the intermittent keyword from java/util/Arrays/ParallelPrefix.java

[Hamlin Li]

bug: https://bugs.openjdk.java.net/browse/JDK-8168505
webrev: http://cr.openjdk.java.net/~mli/8168505/webrev.00/

Test ( java/util/Arrays/ParallelPrefix.java) was failing intermittently, 
related bug (JDK-8080165 
<https://bugs.openjdk.java.net/browse/JDK-8080165>) has been proved not 
reproduced. No open bug and no failure reported.
"@key intermittent" could be removed from test.

Thank you
-Hamlin
