It didn't really fit into any of the existing directories/libraries, so I created a similar one to the legacy HelloWorld example. Since it's unconditionally added to PassRegistry.def, I followed the CMake from something like llvm/lib/Transforms/Scalar. TBH I'm not super familiar with the various CMake machinery, so any suggestions are welcome.

Could it go into llvm/examples or does it need to be under llvm/lib/Transforms?
