> Some opcodes in OPT::HLO are redundant.
> They are unused at all, but there is a code that handls that opcodes.
> For example in Simplifier:
> Opnd*
> Simplifier::simplifyScaledDiffRef(Opnd* src1, Opnd* src2) {
>     if (src1 == src2) {
>     } else {
>     }
>     return NULL;
> }
> Opcodes for review:
> Op_PredCmp
> Op_PredBranch
> Op_ScaledDiff
