Switch to a very conservative heuristic for determining when loop-unswitching will be profitable. This is mainly to remove some cases where excessive unswitching would result in long compile times and/or huge generated code. Once someone comes up with a better heuristic that avoids these cases, this should be switched out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28962 91177308-0d34-0410-b5e6-96231b3b80d8
