Detailed Description
This is a may analysis (i.e.
aliasing that may occur during execution, but is not a given), for global variables. Implemented as a Steensgaard-style analysis, with the Union-find algorithm, for efficiency reasons.

Override this to do custom per-analysis initialization.
Reimplemented from ai_baset.
