[llvm-dev] Have LLD and Clang in their correct locations, but still can't generate project files for LLVM

[Zachary Turner via llvm-dev]

I think most people are using ninja to do the build.  You can still use the
Visual Studio generator for the IDE experience while doing build from
ninja.  I know there are a couple of people who build from inside of Visual
Studio, but it's a pretty small number, and I don't think they are
targeting WebAssembly.
