Now that the 'merge compatible invokes' is effectively done, let's revisit this.

I've reimplemented this using the approach innovated/invented there,
so now not only we don't just tail-merge everything,
not only do we only do that when sinking succeeds,
we now also handle multiple sets of mergeable calls.
