I probably wouldn't recommend it.  I wouldn't want to take the chance
of introducing a wrong-code regression in an attempt to fix a missed
optimization in a minor release.

If someone wants to ponder it further, they'll need to pick up the
tree-ssa-threadupdate changes from earlier this year (to avoid creating
irreducible regions), Diego's vectorizer fix, my reload fix and, of
course the changes to the threading code in tree-ssa-dom.c.
