Isn't this the sam

According to Intel A2 manual, for btx instructions zf is unaffected under any
condition, but for SAR group, when evaluate eflags, we compute zf.
This patch makes zf=
Eflags for bt/bts/btr/btc instructions compute as for shift(SAR) instructions.
According to Intel A2 manual, for btx instructions zf is unaffected under any
condition, but for SAR group, when evaluate eflags, we compute zf.
So I suggest add another group, specifically for computing eflags after
