Description: Add LLVM 7 support
1.Change linking order, as clangCodeGen now links to clangFrontend
2.Pass references not pointers to WriteBitcodeToFile and CloneModule
3.Add the headers that LoopSimplifyID, LCSSAID and
some create*Pass have moved to
4.Define our DEBUG whether or not we just undefined LLVM's
(theirs is now LLVM_DEBUG, but we never actually use it)
