I think this is a very important point. When you succeed showing that tree-ssa
can actually *replace* entire (or big parts of) RTL optimizers, it would be
clear that it's a big win per-se, even if it were not improving SPEC points or
C++ testcases (which is in fact doing).
On the other hand, is there an alternative mission for 3.5? Are there other big
changes which were waiting for Stage 1 to be merged? If we are going to just
bugfix 3.4 and maybe add a couple of new targets, we can as well merge tree-ssa
