LSA and LDSA opcodes are also available with MIPS release 6.
Introduce the decodetree config files and call the decode()
helpers in the main decode_opc() loop.

Now that we can decode the MSA ASE with decode_ase_msa(),
use it and remove the previous code, now unreachable.

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.

The msa_wr_d[] registers are only initialized/used by MSA.
They are declared static. We want to move them to the new
'msa_translate.c' unit in few commits, without having to
declare them global (with extern).
Extract first the logic initialization of the MSA registers
from the generic initialization. We will later move this
function along with the MSA registers to the new C unit.

To allow compiling 64-bit specific translation code more
generically (and removing #ifdef'ry), allow compiling
check_mips_64() on 32-bit targets.
If ever called on 32-bit, we obviously emit a reserved
instruction exception.
