cmd/internal/obj/loong64: add {,X}VS{ADD,SUB}.{B/H/W/V}{,U} instructions support
Go asm syntax:
VSADD{B,H,W,V} V1, V2, V3
VSADD{B,H,W,V}U V1, V2, V3
VSSUB{B,H,W,V} V1, V2, V3
VSSUB{B,H,W,V}U V1, V2, V3
XVSADD{B,H,W,V} X1, X2, X3
XVSADD{B,H,W,V}U X1, X2, X3
XVSSUB{B,H,W,V} X1, X2, X3
XVSSUB{B,H,W,V}U X1, X2, X3
Equivalent platform assembler syntax:
vsadd.{b,h,w,d} v3, v2, v1
vsadd.{b,h,w,d}u v3, v2, v1
vssub.{b,h,w,d} v3, v2, v1
vssub.{b,h,w,d}u v3, v2, v1
xvsadd.{b,h,w,d} x3, x2, x1
xvsadd.{b,h,w,d}u x3, x2, x1
xvssub.{b,h,w,d} x3, x2, x1
xvssub.{b,h,w,d}u x3, x2, x1
