Teach LoopUnswitch not to perform non-trivial unswitching on loops containing convergent operations.
Doing so could cause the post-unswitching convergent ops to be control-dependent on the unswitch condition where they were not before. This check could be refined to allow unswitching where the convergent operation was already control-dependent on the unswitch condition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@249874 91177308-0d34-0410-b5e6-96231b3b80d8
