Fixed a bug in JIT/JITIL. The size_of_merged_addresses variable was being used before it was initialised in certain cases (Rogue Leader).
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
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.
