Is there a PGO tag, or something we can use to increase visibility for PGO reviewers? I think most of the complexity for this new mode is in the PGO code, so I think the best person to review it would be someone with an interest in PGO.

I am aware of this patch and it mostly look good to me. Since there is a long list of reviewers attached to this PR, better give more time for them to chime in.  I am quite busy early part of this week, but will try to give it another round by the end of the week if no one else beats me to it.
