With some additional instructions from Zbp, it seems. Although the document
isn't completely coherent, with various instructions being present in multiple
subsets, and some instructions w/ strike-out.
The B extension requires more than these three, but I suppose turning it on
with just these 3 subsets during development is ok.

Yes, some instructions are striked out and moved to another subset during my implementation.
The B extension spec. is still changing occasionally.
I will send out the next patchset based on your comments.
Thanks for the reviews.
