I had a small epiphany today. If we moved the noise reduction array from
ThreadLocalData into Quant itself:

class Quant {

   NoiseReduction* m_frameNR; // instance per frame encoder, if NR enabled
   NoiseReduction* m_curNR;   // current NR instance, if enabled
   ...
}

setQPforQuant(ctu) could do this:

if (m_frameNr)
   m_curNr = m_frameNr + ctu->m_frame.frameEncoderID;

Then we wouldn't need the ugly setup code in processRowEncoder()
or parallelModeAnalysis()
