A pass to reorder insns so that live ranges are shortened and register

I think you could do this with the scheduler, with appropriate target
hooks. In fact, it sounds like the anti-scheduler.
Hum, searches for "antischeduler" did not bring any result. Sounds like
Cygnus old timers already have a patch for it??? ;-)
It would be curious indeed on the x86 to "antischedule" on the first

the second.
