Since v1:
- Addressed Richard comments (thanks, I learned a lot doing so!
  Although I consider this series 'boring' I enjoyed working on
  your review comments).
- Included Jiaxun R-b tags, but they are conditional on Richard
  ones.

v1 unchanged cover:

Hi,

This series converts 2000+ lines of switch() code to decodetree
description, so this hard-to-review/modify switch is auto generated
by the decodetree script. This is a big win for maintenance (and
indeed the convertion revealed 2 bugs).

Massive convertions are - beside being often boring - bug-prone.
In this series we re-start running the MSA tests (the tests are
run automagically in the 'build-user-static' job on gitlab CI).

Although boring, the conversion is very clean, so I hope it will
be easy enough to review. The TRANS*() macros are heavily used.

When possible, constant fields are hold with tcg_constant().

Note, various opcodes can be optimized using TCG host vectors.
We won't address that in this series, as it makes the resulting
review harder. We will post that in a following series. Here we
simply dummy-convert.

The resulting msa.decode file is quite pleasant to look at, and
the diff-stat is encouraging: number of LoC halved.

Regards,

Phil.
