Duncan Sands 67fb341f8b Fix PR8702 by not having LoopSimplify claim to preserve LCSSA form. As described ...

in the PR, the pass could break LCSSA form when inserting preheaders.  It probably
would be easy enough to fix this, but since currently we always go into LCSSA form
after running this pass, doing so is not urgent.
