[drlvm][jit][opt] Opcode cleanup
--------------------------------

                 Key: HARMONY-2533
                 URL: http://issues.apache.org/jira/browse/HARMONY-2533
             Project: Harmony
          Issue Type: Improvement
          Components: DRLVM
            Reporter: George Timoshenko
            Priority: Minor


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
