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

[Baesken, Matthias]

Hello,

The    test compiler/intrinsics/base64/TestBase64.java

came with JDK-8205528 : Base64 encoding algorithm using AVX512 instructions,  please see

https://bugs.openjdk.java.net/browse/JDK-8205528

This change said to bring performance improvements for java.util.Base64 , however the change seems to include only improvements for Intel x86_64 .
So  currently  we run into timeouts  on some ppc64 machines .

I suggest to increase the timeout  , please see :


Bug :
