test/hotspot/jtreg/compiler/intrinsics/base64/TestBase64.java fails on some ppc64 machines

[Vladimir Kozlov]

Hi Matthias,

This is duplicate of

https://bugs.openjdk.java.net/browse/JDK-8207153

which I am planning to work on soon. Increase timeout is not correct solution. These tests should be run only when 
intrinsics are used.

Regards,
Vladimir
