The Zb[abcs] extensions have complete public review and are nearing ratifications. These individual extensions are one part of what was previously though of as the "BitManip" (B) extension, leaving the final details of future Zb* extensions open as they will undergo further public discourse.
This series updates the earlier support for the B extension by - removing those instructions that are not included in Zb[abcs] - splitting this into 4 separate extensions that can be independently enabled - update the to the 1.0.0 version (e.g. w-forms of rev8 and Zbs instructions no longer exist) Changes in v2: - Fix missing ';' from last-minute whitespace cleanups.
