14f1703ae3 make AliasAnalysis know that VAArg writes memory. This is extremely conservative and should be fixed

8eec644862 if a function doesn't access memory at all, it definitely doesn't read it.

ab8c565768 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.
