Jakob Linke ee0c7f459d Fix CodeMoveEvent 
The invariants in this method are fairly strict since it is called
during object evacution and thus a) objects may be in transitory states
and b) multiple threads are working on evacuation objects concurrently.

Previously, this method ensured valid object accesses because only the
object currently being observed by ProfilingMigrationObserver was
accessed. This changed with crrev.com/c/4178821, where we (incorrectly)
also accessed another object (InstructionStream::code), leading to data
races and incorrect behavior.

This CL fixes that problem by changing LogEventListener API as follows:

 void CodeMoveEvent(InstructionStream from, InstructionStream to);
 void BytecodeMoveEvent(BytecodeArray from, BytecodeArray to);

With this change we again correctly observe invariants, and also remove
one use of AbstractCode.
