That I don't necessarily expect from a JIT in real time. I'd expect it from any half-decent optimizing compiler, but I'd expect it to likely be the result of several interacting and too-expensive-for-real-time optimizations.

I mean, if the JIT works that out, great, and if someone wants to show off performance numbers that shows one can do that I'm interested in the information, but I wouldn't in general discard one for failing to notice that optimization.
