Apple A7 optimizations?

[nex86]

Now that the iOS 7 untethered jailbreak is finally out, how's the chance that ppsspp can be optimized for the A7 processor?
Can we squeeze a few more fps out with 64bit and can the M7 Motion coprocessor be used for PPSSPP ?

The motion coprocessor is for gps trackers and step counters, heh. No use for PPSSPP.

When ARM64-based Android devices arrive, I will spend the time to make a 64-bit JIT to fully utilize the power. I expect a fairly decent speedup as the greater register count means that we will be able to direct map the most common MIPS registers, instead of dynamically allocating them. This will benefit A7 as well.

Sounds great, can't wait to see you work your magic!
