[LLVMdev] compiler-rt with MSVC?

Thanks Reid and Saleem.

I’d prefer to limit my interactions with Visual Studio to cmake and the 
command line if at all possible. The difference in LLVM's build time was 
striking, going through the GUI vs not.

I think builtins should have what I'm looking for here. I was able to get 
Julia to a working REPL with an MSVC build, but some uses of int128 
intrinsics are crapping out.
