target/mips: Introduce decodetree helpers for MSA LSA/DLSA opcodes
...
Add the LSA opcode to the MSA32 decodetree config, add DLSA
to a new config for the MSA64 ASE, and call decode_msa64()
in the main decode_opc() loop.

target/mips: Use decode_ase_msa() generated from decodetree
...
Now that we can decode the MSA ASE with decode_ase_msa(),
use it and remove the previous code, now unreachable.

target/mips: Introduce decode tree bindings for MSA ASE
...
Introduce the 'msa32' decodetree config for the 32-bit MSA ASE.
We start by decoding:
- the branch instructions,
- all instructions based on the MSA opcode.

target/mips: Extract MSA translation routines
...
Extract 2200 lines from the huge translate.c to a new file,
'msa_translate.c'. As there are too many inter-dependencies
we don't compile it as another object yet, but keep including
it in the big translate.o. We gain in code maintainability.
