--- Comment #7 from listmail at philipreames.com ---
Disregard previous comment.  As Simon had previously noted, the original two IR
fragments are not the same.  

The first checks if at least one 64 bit sub-part is zero.  The second checks if
any bit in the 128 bit span is non-zero.  In terms of null checks, the former
is an or of the two sub-parts, the later is an and.
