  This is a particular win for the 386, since it's one instruction.
However, in looking for that construct in code, I conclude that it
doesn't happen often enough to be a big win overall. I'd like to see the
compiler do it as a matter of generating good code, but I wouldn't
expect to see any big change in running time from it.
