r196987 +r197574 +r197572 seems to have done it!

ADTTests works in stage-2 on the powerpc-darwin8-rel-3.4 branch.  I suspect
that TableGen in 15901 will probably work too.
r196987 was just a prerequisite for the latter to apply cleanly.  

Thank goodness, I didn't have to bisect.  It's painful here because
master/trunk doesn't build as-is -- I'd have to repeatedly rebase or merge my
patchset in the bisection process (and builds are slow).
