It looks like ARR is generated, as
src/gallium/state_trackers/nine/nine_shader.c has
#define _OPI(o,t,vv1,vv2,pv1,pv2,d,s,h) \
{ D3DSIO_##o, TGSI_OPCODE_##t, { vv1, vv2 }, { pv1, pv2, }, d, s, h }
[...]
_OPI(MOVA, ARR, V(2,0), V(3,0), V(0,0), V(0,0), 1, 1, NULL),

They've got code for lowering NRM and CND to sanity, and no use of ARR,
ARA, X2D, RFL, STR, SFL, or BRA.
