Current Zero SPARC64 build fails with:

This is a SPARC-specific, Zero-specific, 11u-specific problem.

JDK-8074457 removed the fields with the non-zero C++ interpreter, which broke Zero build:
http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/d321ba06d890#l29.36

Mainline is not affected, because JDK-8244224 removed the SPARC support along with the affected block in bytecodeInterpreter.cpp.

So we just want to fix it in 11u, I think.
