functionally correct port

Hi everyone,

Once the latest pull-requests from Stefan and Djordje get merged, we should have functionally correct LuaJIT AARCH64 port with LJ_GC64 JIT enabled.

What remains to be done is a clean-up effort (w/some small optimizations) before the code can be presented to Mike.

I suggest this to be done by one side only, to avoid different code styles and such issues. I would nominate Stefan and/or Djordje to do this, if no one objects.

What do you say? Ryan?

Regards,

Petar
