This is what LLVM's "LTO" (Link Time Optimization) does, basically. This is
triggered by building with -O4 and you'd need to use an LTO-aware linker
(like gold) to handle the link step. I'm not sure how you'd actually dump
out bitcode from the linker, rather than a final binary - but that's
more-or-less where you'd get involved.

I realize this is a bit vague (as I'm by no means an expert on the matter)
but thought it might be at least a pointer to some ideas/approach.
