Detailed Description

A manager for alias analyses.

This class can have analyses registered with it and when run, it will run all of them and aggregate their results into single AA results interface that dispatches across all of the alias analysis results available.

Note that the order in which analyses are registered is very significant. That is the order in which the results will be aggregated and queried.

This manager effectively wraps the AnalysisManager for registering alias analyses. When you register your alias analysis with this manager, it will ensure the analysis itself is registered with its AnalysisManager.

The result of this analysis is only invalidated if one of the particular aggregated AA results end up being invalidated. This removes the need to explicitly preserve the results of AAManager. Note that analyses should no longer be registered once the AAManager is run.
