+commit e1b2419a0008
+Author: Rebecca N. Palmer <rebecca_palmer@zoho.com>
+Date:   Sat Jul 21 20:05:54 2018 +0100
+
+    Add preliminary LLVM 7 support
+    
+    This is preliminary because LLVM 7 has not been released yet:
+    it was tested with the snapshot from Debian experimental (svn336894).
+    
+    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)
