-`svindex` is a convenience instruction that reduces instruction
-count for Indexed REMAP Mode. It sets up
-(overwrites) all required SVSHAPE SPRs and can modify the REMAP
-area of the SVSTATE SPR as well. The relevant SPRs *may* be directly programmed with
-`mtspr` however it is laborious to do so: svindex saves instructions
-covering much of Indexed REMAP capability.
