The easiest thing to do would probably be to compile LDC against that fork (just point the LLVM_CONFIG CMake variable at their llvm-config binary). Apart from that, not much should be needed per se (apart from adding it as a recognized OS in a couple of places that might report an error otherwise, e.g. in the code that sets the linux/Windows/Darwin/... version definitions).

The thing is they also have a custom clang fork, and I wonder what changes need to be made to the front end (LDC in this case) to fit.
