target/mips: Convert MSA 3R instruction format to decodetree (part 2/4)
Convert 3-register operations to decodetree.
Per the Encoding of Operation Field for 3R Instruction Format'
(Table 3.25), these instructions are not defined for the BYTE
format. Therefore the TRANS_DF_iii_b() macro returns 'false'
in that case, because no such instruction is decoded.
