Convert the following opcodes to decodetree:
- MULT.G - multiply 32-bit signed integers
- MULTU.G - multiply 32-bit unsigned integers
- DMULT.G - multiply 64-bit signed integers
- DMULTU.G - multiply 64-bit unsigned integers
Now that all opcodes from the extension have been converted, we
can remove completely gen_loongson_integer() and its 2 calls in
decode_opc_special2_legacy() and decode_opc_special3_legacy().

- MODU.G - mod 32-bit unsigned integers
- DMOD.G - mod 64-bit signed integers
- DMODU.G - mod 64-bit unsigned integers

DIV.G and DDIV.G are very similar. Provide gen_lext_DIV_G() a
'is_double' argument so it can generate DIV.G (divide 32-bit
signed integers).
With this commit we explicit the template used to generate
opcode for 32/64-bit word variants. Next commits will be less
verbose by providing both variants at once.

Introduce decode_loongson() to decode all Loongson vendor
specific opcodes. Start converting a single opcode: DDIV.G
(divide 64-bit signed integers).
