- 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

With the original script, landmines don't work if the initial commit of the landmine script and the first landmine are in the same build. In this case, the landmine file wouldn't exist yet and no landmine would be triggered. But the updated landmine content would have still been written, omitting the landmine.

Now, the script will initialize an empty landmine file if none exists. This will make sure that a landmine is set on the branch builders after the next branch point.

This also adds some debugging output to better trace when landmines are set/deleted.
