Stalker中优化hook到指令时的log显示格式

• 需求：Frida的Stalker中，希望输出的log日志 -》 尽量模拟之前Xcode的汇编代码的形式
• 核心代码：

    var curRealAddr = instruction.address;
    var curOffsetHexPtr = curRealAddr.sub(funcRealStartAddr)
    var curOffsetInt = curOffsetHexPtr.toInt32()
    var instructionStr = instruction.toString()
    console.log("\t" + curRealAddr + " <+" + curOffsetInt + ">: " + instructionStr);
  

• 输出效果

  +++ into iterator: startAddress=0x104b48470
    0x104b48470 <+16>: stp x22, x21, [sp, #0xc0]
    0x104b48474 <+20>: stp x20, x19, [sp, #0xd0]
    0x104b48478 <+24>: stp x29, x30, [sp, #0xe0]
    0x104b4847c <+28>: add x29, sp, #0xe0
    0x104b48480 <+32>: nop
    0x104b48484 <+36>: ldr x8, #0x104b9c7d8
