We should not call tryOptimizeLEAtoMOV() in eliminateFrameIndex() when
the base register is a virtual register, because tryOptimizeLEAtoMOV
would assume the base register be physical register. Although we can
also optimize LEA to MOV in virtual register, we'll leave the
optimization in another patch.
