That I know of, the TCG plugins do not allow me to feed the QEMU instance
dynamically changing opcodes. I wouldn't use TranslatorOps if I don't have
to. I want to facilitate a use case in which the contents of the target
being emulated are changing, but it is not a self modifying target. I have
to query and interact with the TCG to find out what opcodes are supported
or not.
