Fix a couple of inaccurate stack checks

I observe a 5% runtime performance regression in nofib’s "integer" benchmark: http://ghcspeed-nomeata.rhcloud.com/timeline/?exe=2&base=2%2B68&ben=nofib%2Ftime%2Finteger&env=2&revs=50&equid=on (The graph looks weird because codespeed doesn’t get the order of commits right.) Expected? Or worth looking into?
