I should not change other architectures than AArch64 because 'isArithmeticDivFast' is a new method (only used by this patch). I initially added this logic on AArch64TargetTransformInfo.cpp, but since the division by constant is a platform agnostic transformation I though it would make sense to check the same check on a platform agnostic manner.
