Adding restriction the coprocessor may only decompress valid 16b instrs #206

A |processor| might also attempt to offload compressed instructions that it does recognize as legal instructions itself.

Actually, I am not even sure illegal is the right term here. I think reserved would be more what is intended. On the other hand, the term illegal would better capture 16b segments that are not valid 16b encodings.

So I added a note to clarify, because I think the normative text is already fitting.
