[polly] r246281 - Virtualize the IslNodeBuilder

Log:
Virtualize the IslNodeBuilder

This allows users to extend the IslNodeBuilder to create their own optimization
passes. This feature is not used in Polly's codebase itself, but as these
funtions are not performance critical, the cost of making experiments of
external users easier seems low enough to do so.
