An AdvancedReducer is basically a regular Reducer with an editor that can perform graph editing operations beyond changing or replacing the node that is currently being reduced. The GraphReducer is the default implementation of the AdvancedReducer::Editor interface. The ControlReducerImpl is now just an AdvancedReducer, which temporarily requires a Finish method in the reducer to implement the dead node trimming until we move that to the GraphReducer (which in turn requires that all loops are connected to End).

A diamond is unused if the Merge node has no Phi/EffectPhi uses, exactly two inputs, one IfTrue and one IfFalse, which have the same Branch control input and no other uses except for the Merge. In this case the diamond can safely be removed. R=jarin@chromium.org Review URL: https://codereview.chromium.org/1000883003 Cr-Commit-Position: refs/heads/master@{#27148}

Up until now we used a special Terminate node to artifically connect non terminating loops to the End node, but this was kind of adhoc and didn't work for the CFG. So without all kinds of weird hacks, the end block in the CFG will not be connected to NTLs, which makes it impossible to compute post dominance / control dependence in the current setting. So instead of Terminate, we add a special Branch to NTLs, whose condition is the special Always node, which corresponds to True, except that it cannot be folded away. This way we don't need any special machinery in the scheduler, since it's just a regular Branch.

Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them. This CL is one half of the ControlReducer functionality, the other half being branch folding.
