[Libre-soc-dev] daily kan-ban update 24aug2020

[Luke Kenneth Casson Leighton]

tasks:

* https://bugs.libre-soc.org/showdependencytree.cgi?maxdepth=1&id=383&hide_resolved=1

yesterday: found *another* missing unit test and missing
functionality, in LD/ST: sign-extension opcodes lwa, lwax and lwaux!
also that because i'd not included any ld-with-update unit tests
(untill adding lwaux) i'd managed to break the update code with a
prior commit.

also did a bit more review of dcache.py

today i'll carry on side-by-side running of microwatt 1.bin unit test:
it's by no means perfect, is quite laborious, however does a decent
job of finding errors.
