We must never allow double stores into /u, so this patch instead does
the clearing using non-/u, then emits blockage and then the rest is
with /u.
I'm going to put myself "on record" as saying that I *really* don't like
the "blockage" idea. It's asking for trouble. The conservative setting
of /u for stores is *set*, not clear.
