[Libre-soc-dev] daily kan-ban update 11may2022

[Jacob Lifshay]

I got ieee754fpu.git to pass CI!
https://salsa.debian.org/Kazan-team/mirrors/ieee754fpu/-/jobs/2754033

I marked a bunch of tests with @unittest.expectedFailure with a FIXME
comment explaining what's broken, as well as fixing a few.

I also fixed the CI for nmutil and nmigen-gf and started adding CI to
openpower-isa (doesn't work yet).
