Remove stale documentation about tail duplicaton IR pass

We no longer have a tail duplication pass that runs on LLVM IR. It was removed
in 3.0.

-  This pass performs a limited form of tail duplication, intended to simplify
-  CFGs by removing some unconditional branches.  This pass is necessary to
-  straighten out loops created by the C front-end, but also is capable of
-  making other code nicer.  After this pass is run, the CFG simplify pass
-  should be run to clean up the mess.
