Detailed Description

This is similar to BasicAliasAnalysis, and it uses many of the same techniques, except it uses special ObjC-specific reasoning about pointer relationships.

In this context Provenance'' is defined as the history of an object's ownership. ThusProvenance Analysis'' is defined by using the notion of an ``independent provenance source'' of a pointer to determine whether or not two pointers have the same provenance source and thus could potentially be related.
