Change linking scope for LLVM for the CMake build. Previously PUBLIC was used because I assumed that the LLVM libraries were not contained in Halide dynamic library. This assumption was wrong which meant the linker was being passed the LLVM libraries unnecessarily which could result higher memory use and slower link times.
