Could someone please sponsor the following webrev and push it through JPRT


JIRA issue: https://bugs.openjdk.java.net/browse/JDK-8140238

Zero fails to build after

8136421: JEP 243: Java-Level JVM Compiler Interface


The commit for 8136421 updated headers etc for _sparc, _x86, _ppr and _aarch64 but failed to update _zero.


8078554: Compiler: implement ranges (optionally constraints) for those flags that have them missing


The commit for 8078554 causes zero to generate an error about AllocatePrefetchDistance having the value -1 so I have set this to 0 in vm_version_zero.cpp.

I have posted this to hotspot-compiler rather than build-dev because it is only in the hs-comp tree at the moment and because the build was broken by the commits for the above issues.

Thanks for your help,
