[PATCH v4 00/12] target/mips: Extract MXU code to new mxu_translate.c file

[Philippe Mathieu-Daudé]

Since v3:
- addressed Richard's review comments, elide code when possible

This is a respin of "Extract XBurst Media eXtension Unit
translation routines" v2:
https://lists.gnu.org/archive/html/qemu-devel/2020-11/msg05889.html

But instead of an included C file (.c.inc) we now have an
independent C unit. We gain faster recompilation time when
hacking translate.c or mxu_translate.c, and we also gain
in code maintainability.
