This doesn't make sense. Originally you wanted to add the same
basic-block to multiple functions, which would have been even worse
for separating the two.

Rasha:

It sounds like you want copy-on-write semantics for cloned entities. 
That's a lot of work for very little payoff. You're better off copying 
the bb.
