  Log Message:
  -----------
  [AArch64] Add all cost kinds for integer getArithmeticInstrCost (#210759)

This adds all (CodeSize, Latency, LatSize) costs to
getArithmeticInstrCost integer operations, getting the cost more correct
especially for operations that expand into multiple instructions.
Floating point are left to another commit to limit the impact.
