I forgot I still needed an answer to my original question. :-P

So, I have to implement llvm_gc_initialize, llvm_gc_allocate, and
llvm_gc_collect (llvm_cg_walk_gcroots is provided by the Collector
framework, right?) -- in those methods, how do I access the Collector
object instantiated by LLVM?

(It appears I do have to implement them myself, since otherwise there
are unresolved symbols when I call them directly from my IR)
