LGTM with one very important point.

hvarga has changed the definition of a tablegen class in http://reviews.llvm.org/D19354, so you'll need to make a similar change for SUBU16_MMR6_DESC that was done for ADDU16_MMR6_DESC. Otherwise the instruction selection table is ordered suboptimially and subu16 cannot be chosen.

Thanks.
