Support Mono/LLVM as a runtime/jit

See original GitHub issue

Mono has a special “mode” called Mono/LLVM.

The basic premise with Mono/LLVM is that mono JIT is swapped out for LLVM as a JIT.

It would be great to add support for it in BDN to see how LLVM affects performance (if at all 😃)

I don’t know if there is a programmatic way to detect LLVM support, but here is a hack way…

On my machine, I have both versions of mono installed (With+Without LLVM), here is what mono -V reports:

Without LLVM:

I failed to build mono+llvm, there are some troubles on my linux machine. However, I looked at the source code, it looks fine. =) Let’s assumed that llvm works until somebody sends a bug report. =)

Ok, I will check it.
