Log Message:
-----------
* little POR optimization that can have a significant impact: "synchronized (myfield){..}" is usually compiled
into some "getfield; dup; [astore;] monitorenter" pattern. If we see this pattern (fairly inexpensive test),
we skip the transition break for the getfield and rely on the subsequent monitorenter. Could be more
sophisticated ("Object o = myfield; synchronized(o){..}
