See faster-cpython/ideas#592. This project can be parallelized, and I could use help!

Note that initially we don't have a tier-2 interpreter or instruction format defined yet, but the first stage of splitting doesn't require that.

Remaining non-viable ops

With usage stats from the latest weekly pyperformance run (not all are uop candidates):
