Of course people should realize that -O1 is by no means "maintained" as in
tuned in any way to do something reasonable. At the moment it wastes much
time for no good reason, just selectively turning off some optimizations.
Re-tuning -O1 definitely makes sense - maybe not to the point we'd want to
go with -Odebug.
I'm taking this bug as a request to add -Odebug, something I was working on,
so - mine.
