this clone is supposed to be used for *ALL* of the functions in the SCC. This fixes the memory explosion problem the TD pass was having, reducing the memory growth from 24MB -> 3.5MB on povray and 270MB ->8.3MB on perlbmk! This obviously also speeds up the TD pass *a lot*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20763 91177308-0d34-0410-b5e6-96231b3b80d8
