* These observations imply: offset ≈ index/2
* We use the oparg to fine tune the relation to avoid wasting space
* and allow consecutive instructions to use caches.
*
* If the number of cache entries < number of instructions/2 we will waste
* some small amoount of space.
* If the number of cache entries > (number of instructions/2) + 255, then
* some instructions will not be able to use a cache.
* In practice, we expect some small amount of wasted space in a shorter functions
