Owen Anderson 2f10e78ad1 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.
