This kind of #define-based hack doesn't have a lot of precedent in Clang or LLVM. What is the point of this custom initialization hook? Why does it have to be a #define hacked into the build of Clang itself (which is supposed to be a reusable *library*) rather than being introduced via a plugin or by setting some function pointer/callback somewhere?

This feels very much like the wrong solution for the problem you're trying to solve, but you haven't actually told us what problem you're trying to solve.
