target/mips: Convert MSA 3R instruction format to decodetree (part 1/4)
Convert 3-register operations to decodetree.
Since the 'data format' field is a constant value, use
tcg_constant_i32() instead of a TCG temporary.
Note, the format definition could be named @3rf_b (for
3R with a df field BYTE-based) but since the instruction
class is named '3R', we simply call the format @3r to
ease reviewing the msa.decode file.
However we directly call the trans_msa_3rf() function,
which handles the BYTE-based df field.
