[PATCH 00/17] target/mips: Convert MSA ASE to decodetree

[Philippe Mathieu-Daudé]

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.

While the diff stat is positive by 86 lines, we actually
(re)moved code, but added (C) notices.

The most interesting patches are the 2 last ones.

Please review,

Phil.
