I wouldn't mind that, but I'd also like to point out that there are
Makefiles out there which hard-code things like -fforce-mem. Do we want
to keep the option as a stub to avoid breaking them?

Excellent point.  I believe in other cases we've kept the option
around for a release, then killed it.

I would also like to keep this feature around for a while. It is possible that setting of this option under -O2/-O3 has masked some optimization bugs. In which case, addition of -fforce-mem would be a temporary workaround.
