Extended Description

The AliasSetTracker implements its own Double-linked-list implementation to link all the PointerRec-instances belonging to one Alias-Set.
I think it should reuse an exisiting list implementation.

Honestly, I don't think that the list management code in AST is really the problem. It's a really complex and subtle datastructure, and adding a layer of indirection doesn't help (to me). I'd rather that all existing clients move away from AST so we can remove it.
