I added assembly/simulation support for all bigint ops:
https://git.libre-soc.org/?p=openpower-isa.git;a=commitdiff;h=864d526726aa2ed5497ca6ebe4445a021e16ef9a

I added unit tests for all bigint operations:

I renamed madded -> maddedu for consistency with maddhdu:
https://git.libre-soc.org/?p=openpower-isa.git;a=commitdiff;h=c67ae449d2715354fede681f1f8266df3627d211
https://git.libre-soc.org/?p=libreriscv.git;a=commitdiff;h=6ecafc9cfa1cf13f25fa851d012b20989d770108

I also renamed divrem2du -> divmod2du for consistency with mod* instructions:
https://git.libre-soc.org/?p=openpower-isa.git;a=commitdiff;h=ed9c2e70d09321e94f114914a0c5b9acb4a6fc47
