I have a suggestion, one that I think I made before:

There are two separate cases.

For the not-all-field-specified case, we *have* to do the clearing, but it's
relatively uncommon.  So if TARGET is /u, make a new temporary, do the store
into it in the usual manner, and copy it into the /u TARGET.

In the other cases (mostly_zero), the clearing is an *optimization*. So
suppress it for the /u TARGET.


I'd be OK with that approach. Do you have a patch we can try out?
