; Although we have the ability to fold an unaligned load with AVX
; and under special conditions with some SSE implementations, we
; can not fold the load under any circumstances in these test
; cases because they are not 16-byte loads. The load must be
; executed as a scalar ('movs*') with a zero extension to
; 128-bits and then used in the packed logical ('andp*') op.
