We still need relocates rt_call, not sure why you removed it.
It seem like we need two version of rt_call one with address and one with Address.
Then it seem like we could remove far_call as the rt_call would do the right thing.

I like your idea, and we should do that, but it seems like it's not trivial just to add to this patch.
Is there a reason we need to include such in changes in this PR?
