Remove cycle checking from compute_control_dep_chain

Now that we have DFS_BACK_EDGE marks we can simply avoid walking
those instead of repeatedly looking for a cycle on the current chain.

* gimple-predicate-analysis.cc (compute_control_dep_chain):
Remove cycle detection, instead avoid walking backedges.
