22; We were miscompiling this and using %ax instead of %cx in the movw
23; in the following sequence:
24;	movswl	%cx, %ecx
25;	movw	%cx, (%rsi)
26;	movslq	%ecx, %rcx
27;
28; We can't produce the above sequence without special SD-level
29; heuristics. Now we produce this:
30; CHECK: movw	%ax, (%rsi)
31; CHECK: cwtl
