e4c6f9488e Implement graph trimming in ControlReducer. 
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.

b80e76841e Remove a brittle assertion from Turbofan lazy deoptimization handling. 
As discussed in person with Benedikt, it is better to remove the assertion because it is too brittle. The assertion says that the continuation block should immediately follow the call. However, there are exceptions - such as nop or constant pool in-between being fine - that make the assertion brittle.

9523e0acf4 re-land: Track history of events in GCTracer. 
- track incremental marking stats directly on GCTracer.
- add simple ring buffer class.
- track last 10 scavenges and mark-compacts in ring buffers on GCTracer.
- various clean-ups.

This is a re-land of https://codereview.chromium.org/391413006/ with
 - int instead of size_t in ring buffer unit test.
 - git cl format
