Core/DSPCore: Make JIT work on 64 bit hosts 

This is the safe variant that does not assume other
functions use R11 for &g_dsp.r, which they actually do.
So there is a lot unnecessary reloading of the register
getting emitted.

There are a few small changes exploiting pointers known
at emission time and making use of MComplex math.

Also renames m_LLEplaying to m_AIplaying in Core/AudioCommon.
