-x86 BZHI semantic bug
-Description of problem:
-The result of instruction BZHI is different from the CPU. The value of destination register and SF of EFLAGS are different.
-Steps to reproduce:
-1. Compile this code
-```
-void main() {
-    asm("mov rax, 0xb1aa9da2fe33fe3");
-    asm("mov rbx, 0x80000000ffffffff");
-    asm("mov rcx, 0xf3fce8829b99a5c6");
-    asm("bzhi rax, rbx, rcx");
-}
-```
-2. Execute and compare the result with the CPU.
-    - CPU
-        - RAX = 0x0x80000000ffffffff
-        - SF = 1
-    - QEMU
-        - RAX = 0xffffffff
-        - SF = 0
-Additional information:
-This bug is discovered by research conducted by KAIST SoftSec.
