Oh dear, I can't really find any good place to bind the variable either, but 
ended up doing it in `byte-compile-inline-expand` on the grounds that it's the 
only place we re-enter the compiler from the optimiser.

It would probably be better if we had a single entry for `byte-optimize-form` 
that wasn't used recursively; then it could be done there.

Anyway, feel free to improve. Writing the test was what took most of the time 
anyway!
