[aarch64] - Only use MOV for disassembly when shifter op is LSL #0
ARM Architecture Reference Manual for the profile ARMv8-A, Issue C.a,
states that MOV (register) is an alias of the ORR (shifted register)
iff shift == '00' && imm6 == '000000' && Rn == '11111'. However, mov
is currently preferred for a broader range of orr instructions, which
is incorrect.
