The interesting part of this is in WebRemoteFrameClient::changeLocation,
where we call dispatchDecidePolicyForNavigationAction which I've made able
to handle a RemoteFrame, and if the result is PolicyAction::Use then we
call transitionToLocal then changeLocation which begins the provisional
load in this process.  A lot of things aren't quite hooked up completely
yet, but the progress is testable.
