At this point it looks like a B extension will never exist. Instead the various bitmanip extensions will be ratified individually.

This patch removes references to the B extension. I've updated and split tests accordingly.

This has been split from D110669 <https://reviews.llvm.org/D110669> to make review a little easier.
