Super Constructor Calls need to use a vector slot, not an ic slot.

Super Constructor Calls need to use a vector slot, not an ic slot.

The Ast Call node is accustomed to using a vector IC slot for the
cases when it uses a CallIC. The super constructor work alters this
somewhat by using a CallConstructStub instead, however the
CallConstructStub expects a vector slot and not a vector ic slot.
This distinction needs to be maintained because slots and ic slots
have different clearing strategies and are handled differently.

Can you have a look at this? It is a fix for an interesting super constructor
issue. Thanks very much!
