I think outlining from functions with streaming-mode changes needs more
investigation. I don't think this is just a concern for async unwind; I noticed
that when passing `-enable-machine-outliner` to sme-vg-to-stack.ll that some
calls are outlined with only one of the smstart/smstop instructions surrounding
the call. I'm not sure if this is safe yet, so for now I've disabled outlining
for these functions in `isFunctionSafeToOutlineFrom`.
