* Add support for DataStructure analysis
...
* Parameterize pass outputting with the printPass template, so analysis
output can optionally take more arguments than just a stream. The
default output mode is just to use operator<< on the analysis.
* Remove CurrentModule hack, in favor of using printPass
* Remove special operator<<'s defined for FindUsedTypes and
FindUnsafePointerTypes, in favor of printPass specializations
* Use std::cout instead of cout
