`offs` is defined as CR48 (6x8) so as to mesh cleanly with Vectorised Rc=1 operations (see below). Arithmetic Rc=1 operations start from CR16 (TBD); FP Rc=1 from CR32 (TBD).

This is a novel concept that allows predication to be applied to a single
source and a single dest register. The following types of traditional
version of VCOMPRESS-VEXPAND which is effectively the ability to do an

## CR Operations
CRs are slightly more involved than INT or FP registers due to the
