Updating robovm-llvm to use llvm 3.4


llvm 3.3 has a bug on a windows https://groups.google.com/d/msg/robovm/DjJzboTBVOA/Uu4MPCQcwRsJ

Hopefully, using llvm 3.4 fixes that.
I'm not sure that including the dll is the proper thing to do, but here you are.
Feel free to delete what is not relevant.

By the way, I am not sure that the current vm layout is appropriate: resources/windows/86 may contain the cross compilation dll you built and the windows-on-windows that I built.
Are those interchangeable?
