libLLVMSharp

[ds5678]

As I mentioned in #222, I have interest in expanding the C# API, which requires a custom library similar to libClangSharp, ie libLLVMSharp. Do you have any guidance about how you want that implemented and what you want it to contain?

So far, my implementation is fairly bare-bones. I added two methods:

• llvmsharp_Function_getFunctionType
• llvmsharp_Function_getReturnType

I've been working on an IR -> CIL translation project, and these two methods have helped a lot.
