 When `vf=1` then stepping occurs. When `vf=0` svstep may be used
 to enquire about the REMAP Schedule, without altering internal
 state.  If `SVi=0, Rc=0, vf=0` this instruction is a `nop`.

 To obtain the full set of possible computed element
 indices use `svstep RT.v,SVI,1` which will store all computed element
 indices, starting from RT.  If Rc=1 then a co-result Vector of CR Fields
