[llvm-dev] llvm.natvis should be included when generating LLVM.sln

[<Alexander G. Riccio> via llvm-dev]

I haven't gotten around to this yet because I have some annoying issue with
my installation of git (CMake uses git), but I love the idea of whipping up
a 10 line patch, and hope to get around to it soon!

Assuming you did it that way, the way you would trigger this in CMake is to

Ahh, this CMake thing is starting to make sense now.

Sincerely,

If left to my own devices, I will build more.
