These all had approval with requested changes, so these are now collected together for v2. Note that this adds the (a & ~C) case, so please take a look on that part and OK the updated series. Changes in v2: - Collects already approved changes for v2 for (a | C) and (a ^ C). - Pulls in the (already) approved branch on polarity-reversed bits for v2, as it shares predicates with the other changes. - Newly adds support for the (a & ~C) case.
