Will we be able to add the main-thread WebPerformance code to this module as
well?  My understanding is that at least some of it is tightly coupled with
FrameLoader and other core classes...

Yes, that's the intent. The first thing I want to do is move all of the
page/Performance* files here.

Moving the stuff in loader/ will be harder as you say. I don't have a plan for
that right now.
