Description
After JDK-8335860, we see a lot of timeouts in test compiler/vectorization/TestFloat16VectorConvChain.java 
on the ppc64 based platforms.
The timeouts show up especially with the (fast)debug binaries.

Very long runtimes were also observed on s390x. Seems some implementation is missing on ppc and s390x, that#s why the performance of the test is very bad on those platforms.
