extractor has extracted hundreds of loops from the SPEC benchmarks without crashing and without misoptimizing the programs. This testcase could be reduced substantially more by hand, but I don't have time to work on it right now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12495 91177308-0d34-0410-b5e6-96231b3b80d8
