cmd/internal/obj/loong64: add {V,XV}DIV{B/H/W/V}[U] and {V,XV}MOD{B/H/W/V}[U] instructions support

Browse source 
Go asm syntax:
	 VDIV{B/H/W/V}[U]	VK, VJ, VD
	XVDIV{B/H/W/V}[U]	XK, XJ, XD
	 VMOD{B/H/W/V}[U]	VK, VJ, VD
	XVMOD{B/H/W/V}[U]	XK, XJ, XD

Equivalent platform assembler syntax:
	 vdiv.{b/h/w/d}[u]	vd, vj, vk
	xvdiv.{b/h/w/d}[u]	xd, xj, xk
	 vmod.{b/h/w/d}[u]	vd, vj, vk
	xvmod.{b/h/w/d}[u]	xd, xj, xk
