Hmm...  Let's concentrate on poorly analyzed 3.3 regressions; it'd be
really cool if you have time to hunt these down:

opt/10087 [3.3/3.4 regression] optimizer produces wrong code when indexing 2D array
c++/10047 [3.3 regression] -fno-default-inline produces bogous warnings
opt/9123  [3.2/3.3/3.4 regression ] Internal compiler error in do_SUBST at combine.c:434

They have not been analyzed beyond "confirmed" (which should have its
own state BTW).  If you'll take a shot at some of these, please let me
know and I'll add a note to the audit trails of the PRs.
