It is a prerequisite for -disable-iv-rewrite performance. It is also easily handles loops of arbitrary structure including multiple exits and is generally more robust. This is under a temporary option to avoid affecting default behavior for the next couple of weeks. It is needed so that I can checkin unit tests for updateUnloop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137384 91177308-0d34-0410-b5e6-96231b3b80d8
