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. llvm-svn: 28962
