[Bug tree-optimization/41026] invariant address load inside loop with -Os.

Hmm, this isn't my day.  Of course you're right, Andrew.

So the issue is that a loop invariant load is not hoisted at -Os, because it
does not improve size.

FWIW several patches have been proposed to change this, see e.g.:
