UaF outside the sandbox in RenderFrameDevToolsAgentHost::RevokePolicy

Reported by wadih.ma...@gmail.com, Sep 30 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36

Steps to reproduce the problem:
1- http://localhost/poc/run.html
2- Social engineer the victim into pressing F12 (opens devtools)

What is the expected behavior?
No Browser crash

What went wrong?
During a cross process navigation, if devtools is opened (or already opened), RenderFrameDevToolsAgentHost::RevokePolicy can be forced to manipulate a freed object ( RenderProcessHost?) in the browser process.

Did this work before? N/A 

Chrome version: 61.0.3163.100  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: 

Also works on chrome 63.0.3227.0 (Official Build) canary (64 bits)
