HL2 JIT

[ncannasse]

This is a WIP branch with a new JIT using an Intermediate Representation (IR) and optimized register allocation.
This will allow more easy maintain, ports to ARM or other CPUs, and better runtime performances

@bmdhacks this new version is passing haxe unit tests. It still have a few issues that I need to investigate and I need to update debugger support but it's a good basis for ARM support as only the code generator needs to be swapped (and maybe a few fixes here and there).

Cool I'll take a look. Are you interested in any pull requests from me to add some functionality that my jit has that's missing here?

I'm still a bit in the middle of development, but if I have time to integrate them yeah. What kind of thing were you missing?

Ok, but did you want me to port my aarch64 jit to this IR, or were you wanting to do it yourself?

I'll leave the arm support to you 😉
