While the comment is correct to state that this won't enable any new optimizations with -Onone, it does enable IRGen's lazy function emission, which is important for 'reasync' functions, which we don't want to emit at all even at -Onone. This fixes debug stdlib builds with the new reasync versions of the &&, || and ?? operators.
