This CL fixed cmpq in TestMoveSmi by using cmp_tagged and further
optimizes Move(Register, Smi) for 31-bit negative Smi.

To move a Smi of -1 to register, the disassembly before the commit is as:
48c7c0feffffff    REX.W movq rax, 0xfffffffe

The disassembly after the commit is as:
b8feffffff        movl rax, 0xfffffffe
