Several *major* changes to the AA interfaces:
...
1. Provide interfaces so that clients can update alias analyses to reflect
the changes made by the transformations.
2. Change how alias analysis implementations work overall. In particular,
now clients will automatically forward to chained AA implementations: they
don't have to remember to do it themselves.
