* Uses asm to add the stack map attribute to methods in a class. The class is passed in as pure byte data and then a reader/writer
* process it. The writer is wired into the world so that types can be resolved and getCommonSuperClass() can be implemented without
* class loading using the context class loader.

*
* It is important that the constant pool is preserved here and asm does not try to remove unused entries. That is because some
* entries are refered to from classfile attributes. Asm cannot see into these attributes so does not realise the constant pool
* entries are in use. In order to ensure the copying of cp occurs, we use the variant super constructor call in AspectJConnectClassWriter
* that passes in the classreader. However, ordinarily that change causes a further optimization: that if a classreader sees
* a methodvisitor that has been created by a ClassWriter then it just copies the data across without changing it (and so it
* fails to attach the stackmapattribute). In order to avoid this further optimization we use our own minimal MethodVisitor.
