[PATCH v2 00/24] target/mips: Convert MSA ASE to decodetree

[Philippe Mathieu-Daudé]

Missing review: 1-3 14 17 19-24

Since v1:
- rebased
- addressed Richard review comments
- reworded some commit descriptions
- avoid 64-bit ifdef'ry

Finally, we use decodetree with the MIPS target.

Starting easy with the MSA ASE. 2700+ lines extracted
from helper.h and translate.c, now built as an new
object: mod-msa_translate.o.
