4d6624b430 8057696: java -version triggers assertion for slowdebug zero builds 
The change as introduced with JDK-8003426 removed some zero code in cppInterpreter_zero.cpp which called generate_normal_entry() in that same file with a value of synchronized == false unconditionally. However, since the new code calls generate_normal_entry() with either true or false, the assertion in this method is no longer valid.
