Thomas Van Lenten 13a41246dd Make Root's +extensionRegistry generation smarter.
At generation time, walk the file's dependencies to see what really contains
extensions so we can generate more minimal code that only links together the
roots that provided extensions. Gets a bunch of otherwise noop code out of
the call flow when the roots are +initialized.
