What are you talking about with the zerosleft decoding? It
is merged with dequantization, and is not two loops (and I don't think this was done recently either).

Would you like to point me to a specific case so I can fix it rather than complaining?
Any suggestion for improved context calculation performance will probably allow me to make x264's RDO faster as well.
Same with the actual CABAC decoding--are you suggesting that there is a better way to organize LUTs/similar that results in better faster arithmetic decoding than what LAVC already has?
