LLVM indeed provides this feature; in fact, that's the entire point of 
the intrinsic in question.

The problem is that inline IR support was not written with this sort of 
dependencies in mind (and I don't see us making any stability guarantees 
for the generated IR, e.g. that "foo:" is always lowered to %label_foo).

It might be possible and reasonable to delay emitting any inline IR 
wrapper function bodies until after the main function has been 
completed. In fact, it shouldn't even be too difficult to throw together 
a quick implementation, but unfortunately, I don't have the time to look 
into this right now.
