This reduces e main module size by ~ 0.5-1% When compiling with deferred loading, we optimize each module individually with open world assumptions. Currently we run only one -Os pass which leaves code behind that can be optimized by another -Os. See e.g. discussion at [0]. The additional -Os pass is much faster than the first, so it doesn't add meaningful compile-time.
