This is a good clean up.  JDK_GetVersionInfo0 was needed long time ago 
in particular in HS express support that is no longer applicable.

One leftover comment should also be removed.

src/hotspot/share/runtime/vm_version.hpp
   // Gets the jvm_version_info.jvm_version defined in jvm.h

otherwise looks good.
