cmd/internal/obj/loong64: add {V,XV}{ADD/SUB}.{B,H,W,D,Q} and {V,XV}{ADD/SUB}.{B,H,W,D}Uinstructions support

Browse source 
Go asm syntax:
	 V{ADD/SUB}{B,H,W,V,Q}		VK, VJ, VD
	XV{ADD/SUB}{B,H,W,V,Q}		XK, XJ, XD
	 V{ADD/SUB}{B,H,W,V}U		$1, VJ, VD
	XV{ADD/SUB}{B,H,W,V}U		$1, XJ, XD

Equivalent platform assembler syntax:
	 v{add/sub}.{b,h,w,d,q}		vd, vj, vk
	xv{add/sub}.{b,h,w,d,q}		xd, xj, xk
	 v{add/sub}i.{b,h,w,d}u		vd, vj, $1
	xv{add/sub}i.{b,h,w,d}u		xd, xj, $1
