It also breaks nearly every test in SPEC 2k and 2k6 ;)

proposed patch

In the description for the patch in question, I mentioned how during
stage1 we could clean up all these patterns to rely on LRA.  The fact
that this pr was filed immediately suggests that the current setup is
quite difficult to follow.

Cleaning this up now instead of waiting for stage1 would seem to be
the way to make sure we get all the cases right.
