cmd/internal/obj/loong64: add ll.acq.{w,d}, sc.rel.{w,d}, sc.q instruction

Go asm syntax:
	LLACQW	(RJ), RD
	LLACQV	(RJ), RD
	SCRELW	RD, (RJ)
	SCRELV	RD, (RJ)
	SCQ	RD, RK, (RJ)

Equivalent platform assembler syntax:
	ll.acq.w	rd, rj
	ll.acq.d	rd, rj
	sc.rel.w	rd, rj
	sc.rel.d	rd, rj
	sc.q		rd, rk, rj

To ensure semantic consistency of instruction suffixes, equivalent
instructions LLW and SCW for LL and SC have been added.
