OOPIF: Investigate RenderViewHost reuse issues

Project Member Reported by alex...@chromium.org, Apr 26 2016 
We currently have cases where the RenderViewHost is reused across navigations and some of its state might become stale.  For example, if we navigate from A-embed-B to B, the swapped-out RVH for subframe B will be reused for the new page on B.  After https://codereview.chromium.org/1886413002/, we will also allow reuse of a RVH from a pending delete RFH, leading to more such cases.  The concern is that in these cases some of the RVH fields might become stale (enabled_bindings_, sudden_termination_allowed_, is_waiting_for_close_ack_, etc.).  main_frame_routing_id_ is going to be stale until commit, though that currently doesn't cause anything to break.  We should investigate these reuse issues further and watch out for bugs due to them.  See the full discussion at https://codereview.chromium.org/1886413002/diff/180001/content/browser/frame_host/frame_tree.h#oldcode242

This still needs investigation.  At least the main_frame_routing_id_ staleness came up in issues 627400 and 627893.

There are also issues with reusing the RenderWidget (which is currently the same as the RenderView), for example issues  638375  and  701988 .

This is still work we want to do, so removing Hotlist-Recharge-Cold.
