[gandiva] floating point division shouldn't cause errors

[asfimport]

for division, gandiva explicitly checks if the divisor is zero and raises an error.

This is correct for integer division. For float point divisions, it should just return infinity.

I checked Oracle, SQLServer and PostgreSQL - all of them throw a divide-by-zero for floating point types too. So, the current behavior of gandiva is already correct.
