[drlvm][jit] Incorrect generated instruction in peephole opt for MOV
--------------------------------------------------------------------

                 Key: HARMONY-6024
                 URL: https://issues.apache.org/jira/browse/HARMONY-6024
             Project: Harmony
          Issue Type: Bug
         Environment: IA32 Windows
            Reporter: Xiaoming Gu


In the case 1 of peephole opt for MOV in Ia32PeepHole.cpp, the optimization is like following:

        MOV opnd, opnd2             MOV opnd3, opnd2
        MOV opnd3, opnd      =>

The bug is the new MOV instruction is always generated by "newInst" even the original MOV
instructions are both pseudo copy, which will cause an assertion error later.
