- 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 R=hpayer@chromium.org BUG= Review URL: https://codereview.chromium.org/411293002 git-svn-id: https://v8.googlecode.com/svn/branches/bleeding_edge@22593 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
