[Libre-soc-bugs] [Bug 1068] add instructions from ls012 not currently implemented in binutils

--- Comment #29 from Jacob Lifshay <programmerjake at gmail.com> ---
I checked all the instructions in ls012/optable.csv against the simulator and
the svp64 branch of binutils. I edited the top comment to include my results. I
also noticed that divmod2du is marked in ppc-opc.c to be in POWER9, not SFFS,
so that needs to be fixed.

I also fixed some typos I discovered in optable.csv:

    rename shadd* -> sadd* in ls012/optable.csv to match ls004

Including the full opcode list here too for future reference:

divmod2du (needs fixing to use SFFS not POWER9)
