Build LLVM Project on Windows

[tim-pugh]

Considering there is two methods to layout records (one for unix and one for MS based systems), we need to consider getting a build of LLVM working on windows.

Instructions are here:

I've been getting a machine prepped. I can't say if this will work or not considering the instructions are a bit complex, but I'm giving it a go.

Instructions are on the team drive, build completed successfully.

I'm next working on swapping the VS toolchain to clang. It turns out there appears to be some easy steps on accomplishing this:

https://releases.llvm.org/download.html (look for the windows binary 64 bit installer)

Right now, I'm building the simple test program to see if it is truly working correctly from this guide:

Using gnuwin32 I was able to build a simple hello world program written in C and output a .exe so as far as I know things are working correctly (at least according to the guide).

Built on windows, will test programs in a separate issue.
