[PATCH 00/13] target/mips: Convert LSA/DLSA and part of the Rel6 removed opcodes

[Philippe Mathieu-Daudé]

Complete the MSA conversion with the LSA/DLSA opcodes,
which are shared with the Release 6.

Keep going converting the removed opcodes.

We now have 2 decoders on 32-bit, and 4 on 64-bit.

Extensions are decoded first, then ISA.

I might introduce a macro to have a generic decode()
function to hide the 32/64 check, to keep the main
decode_opc() loop easy to review.

Regards,

Phil.
