It's mainly trying to find the low-hanging fruit. For example, objects that never escape the current stackframe and thus can be the target of scalar replacement.  It does some other simple analysis too, but the main motivation in the current system is to enable the transformations in EscapeTransformations (synchronization removal and scalar replacement of object/small arrays).
