The "mask" stored in the cache of COMPARE_OP could be stored in the oparg.

[markshannon]

The "when to branch mask" used by specializations of COMPARE_OP takes 4 bits, the comparison operator take 3 bits.
Since the mask can be computed at compile time, it should be stored in the oparg along with the comparison operator.
This would free up a cache entry.
