Bitwise Bit Clear (shifted register) performs a bitwise AND of a register value and the complement of an optionally-shifted register value, and writes the result to the destination register.

位清除（移位寄存器）执行寄存器值与可选移位寄存器值的补码的位与，并将结果写入目标寄存器。

32-bit variant
    Applies when sf == 0.
    BIC <Wd>, <Wn>, <Wm>{, <shift> #<amount>}

64-bit variant
    Applies when sf == 1.
    BIC <Xd>, <Xn>, <Xm>{, <shift> #<amount>}

Operation
 bits(datasize) operand1 = X[n];
 bits(datasize) operand2 = ShiftReg(m, shift_type, shift_amount);
 
 operand2 = NOT(operand2);
 
 result = operand1 AND operand2;
 X[d] = result;

bic r0, r0, #%1011 // 清除 r0 中的位 0, 1, 3, 其余的位保持不变.
