  [AArch64] Build v2i64 Mul cost out of getArithmeticInstrCost and getVectorInstrCost. NFCI

This should not effect the result, unless the getArithmeticInstrCost and
getVectorInstrCost routines learn to produce different costs (with CostKind =
CodeSize for example). The -1 lanes prevent 0 lanes from (incorrectly) being
marked as free.
