I suggest excising the TARGET_PARTIAL clauses ASAP, and reinstating them only
when alignment checking (and/or something else) is used in them to verify that
the transform is safe. That seems to be the most correct thing to do.
If someone is up to writing the alignment checking right now, of course,
that's great, but I'm not!
