Krisztian Szucs updated ARROW-9022:
-----------------------------------
Description:
-Currently the output type of the Add function is identical with the argument
types which makes it unsafe to add numeric limit values, so instead of using
{{(int8, int8) -> int8}} signature we should use {{((int8, int8) -> int16}}.-
The current kernels do wrap around for performance reasons, so implement
different kernels with overflow checking and add arithmetics options to let the
caller choose which variant to run
