[PATCH] [cmake] Unbreak LLVM-Config.cmake / llvm_expand_dependencies

[Peter Zotov]

The new implementation was tested in the CMake buildsystem of the OCaml bindings, which I will post a bit later. It links a lot of libraries in different combinations, which, with BUILD_SHARED_LIBS=OFF, exposed both the incorrect ordering and the hangups in the old implementation. The new one works perfectly well.
