Remove minimal CFG sanity checks from verifier.
These checks would often trigger on unreachable statements inserted by bugpoint, leading it astray. It would be nice if we could distinguish unreachable blocks from errors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91923 91177308-0d34-0410-b5e6-96231b3b80d8
