[Patch ARM] Update the test case to differ movs and lsrs for ARM mode and non-ARM mode

[Terry Guo]

Hi,

Due to the impact of ARM UAL, the Thumb1 and Thumb2 mode use LSRS
instruction while the ARM mode uses MOVS instruction. So the following case
is updated accordingly. Is it OK to trunk?

BR,
Terry

        and lsrs for other mode.
