I found what appears to be a solution for the problem without having to
break the file.
Removed a bunch of template instantiations from the marshaller functions.
In particular, std::list<Matcher<T>> and std::vector<Matcher<T>*> for each
node T. Just that one change seemed to take the unit below the limit.
Sent the change on http://llvm-reviews.chandlerc.com/D948. If you want,
please patch the change and let me know if it fixes the issue. I don't have
that environment, so I can't test it there.
