 With the scalar OpenPOWER v3.0B ISA having already popcnt, cntlz and others normally seen in Vector Mask operations it makes sense to allow *both* scalar integers *and* CR-Vectors to be predicate masks.  That in turn means that much more comprehensive interaction between CRs and scalar Integers is required.
 
+The opportunity is therefore taken to also augment CR logical arithmetic as well, using a mask-based paradigm that takes into consideration multiple bits of each CR (eq/lt/gt/ov).  v3.0B Scalar CR instructions (crand, crxor) only allow a single bit calculation.

 Basic concept:
 
 * CR-based instructions that perform simple AND/OR/XOR from all four bits
