Please review:


Bug: For classfiles before class file version 51, JVMS did not support transitive over-ride behavior. 
Implementation needed to check this in three places, not just one. Vtable size calculation is only exact
for later classfile versions.

Also fixed vtable logging output - since the method name-and-sig printing was changed to also print
the holder’s class name, we do not need to print the holder’s class name separately - it was printing twice.

Testing: linux-x64-slowdebug
rbt hs-nightly-runtime.js
jck vm,lang, api.java.lang
small invocation tests
