LLVM BC as library

[Void-995]

Some time ago I was able to compile simple library into BC (pure 
C) and load it with my application and use across different 
operating systems with re-compilation having those external code 
running in a sandbox.

How much difficult it would be to try with D? Means application 
is in C++ and I want to load BC made from D code?

The idea itself comes from something like sandboxed Quake 3 QVM 
and used for game logic, it's pretty easy to replicate that 
behavior with C/C++ with LLVM BC. I wonder how much pain it would 
be to make that with D instead.
