This is a work in progress. So far we have some basic loop analysis to help

leaks though) and add methods to its interface for adding/finding specializations.
Simplifies its users a bit and we no longer need to replace specializations in the folding set with
their redeclarations. We just return the most recent redeclarations.
As a bonus, it fixes http://llvm.org/PR7670 .
