cmd/internal/obj/loong64: add {,X}VSLT.{B/H/W/V}{,U} instructions support

Browse source 
Go asm syntax:
	 VSLT{B,H,W,V}    V1,   V2, V3
	 VSLT{B,H,W,V}U   V1,   V2, V3
	 VSLT{B,H,W,V}    $-2,  V2, V3
	 VSLT{B,H,W,V}U   $8,   V2, V3
	XVSLT{B,H,W,V}    X1,   X2, X3
	XVSLT{B,H,W,V}U   X1,   X2, X3
	XVSLT{B,H,W,V}    $-16, X2, X3
	XVSLT{B,H,W,V}U   $31,  X2, X3

  Equivalent platform assembler syntax:
	 vslt.{b,h,w,d}    v3, v2, v1
	 vslt.{b,h,w,d}u   v3, v2, v1
	 vslti.{b,h,w,d}   v3, v2, $-2
	 vslti.{b,h,w,d}u  v3, v2, $8
	xvslt.{b,h,w,d}    x3, x2, x1
	xvslt.{b,h,w,d}u   x3, x2, x1
	xvslti.{b,h,w,d}   x3, x2, $-16
	xvslti.{b,h,w,d}u  x3, x2, $31
