(The message in question is 
http://lists.llvm.org/pipermail/llvm-dev/2015-October/091128.html , for 
reference.)

The problem is that you can't require a FunctionPass from a ModulePass.  
The solution is not to do that.

createLegacyPMAAResults is an alternative way to access alias analysis 
without an AAResultsWrapperPass.  See the LLVM source code for examples 
of how to use it.
