Apple A7 optimizations?

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.
