`BO` as a set) dictate that the Branch should take place on either 'ALL'
tests succeeding (or failing) or whether 'SOME' tests succeed (or fail).
These options provide the ability to cover the majority of Parallel
-3D GPU Conditions, saving a not inconsiderable number of instructions
+3D GPU Conditions, saving up to **twelve** instructions
especially given the close interaction with CTR in hot-loops.[^parity]
[^parity]: adding a parity (XOR) option was too much. instead a parallel-reduction on `crxor` may be used in combination with a Scalar Branch.
