KOS_OP_TAIL_CALL_FAST_ATTR_STAR

• Style: EXTRA. Schema: FASTVAR (slot for obj), CONST (attr name), COUNT (opa bitflags), NOARG. One cache slot.

• Stack: Same layout and pop order as CALL_FAST_ATTR_STAR; the call is a tail call, so the caller’s frame is reused rather than a new frame pushed.

• Compiler form: Fast tier of TAIL_CALL_VAR_ATTR_STAR; see KOS_OP_TAIL_CALL_FAST.
