Well, it is actually very much related to that reversion. While it didn't
regress in between 161907 and 162617, it regressed from the MEM_REF merge till
161906 and from 162618 onwards.
The problem is that due to the MEM load combiner isn't able to fix this up, so
if we don't get it right during expansion, we are out of luck. Looking at it
now...
