Makes sense to move the PassPlugin support out of Passes.

If I understand correctly, the current role of the Extensions component is to link in statically linked plugins. I guess moving PassPlugin there makes sense in that it would ensure that any tool that supports plugins also links the static plugins. But I'm not really familiar with how all of this is set up.
