This is certainly a cool idea. I played around with this, and I think
we should be able to get it to work. However, this won't work for the
LTO case, because dwarf2out currently works just as our pre-debug-early
world did. We don't have an early DIE we can annotate later. At least,
until we get Richi's DIE streaming idea working.
We could temporarily make the LTO case behave like early-debug by
emitting early DIEs after LTO stream in-- while we get DIE streaming
implemented, or we could leave the DECL_ABSTRACT redesign
post-richi-streaming. I'm leaning towards the latter.
Thoughts?
