cmd/internal/obj/loong64: add {V,XV}MUL{B/H/W/V} and {V,XV}MUH{B/H/W/V}[U] instructions support
Go asm syntax:
VMUL{B/H/W/V} VK, VJ, VD
VMUH{B/H/W/V}[U] VK, VJ, VD
XVMUL{B/H/W/V} XK, XJ, XD
XVMUH{B/H/W/V}[U] XK, XJ, XD
Equivalent platform assembler syntax:
vmul.{b/h/w/d} vd, vj, vk
vmuh.{b/h/w/d}[u] vd, vj, vk
xvmul.{b/h/w/d} xd, xj, xk
xvmuh.{b/h/w/d}[u] xd, xj, xk
