Interesting. This seems to be a somewhat recent addition, and the
mailing list discussion linked to above predates it. Coincidentally, I
pulled a copy of the Intel manuals at almost exactly the same time as
this discussion, and sure enough, it does not yet contain the
paragraph about 16 byte operations.
