-CR based predication. TODO: select alternate CR for twin predication? see
-[[discussion]] Overlap of the two CR based predicates must be taken
-into account, so the starting point for one of them must be suitably
-high, or accept that for twin predication VL must not exceed the range
-where overlap will occur, *or* that they use the same starting point
-but select different *bits* of the same CRs

`offs` is defined as CR32 (4x8) so as to mesh cleanly with Vectorised
Rc=1 operations (see below). Rc=1 operations start from CR8 (TBD).
