[Soot-list] Correct insert of JIfStmt

[Julien Klaus]

Hello Steven and Marc,

I think it is posible to insert a clone of a statement. The clone() 
funtction for the statements returns a new
object and so the hashcode is unique.
When I try to insert a unit (without clone it before) I get an 
/java.lang.RuntimeException: Chain already contains object./ error.
Because of this i clone every unit before I insert it in the chain.

I need to insert copies for example for loop unrolling. The problem 
occours when the clone
is an instance of for example JIfStmt. There my graph get broken and I 
can not repair it.
I think in this case the chain can not redirect the pointers. I hope my 
problem is now better explained.

Best regards,
Julien
