Review comment:
There is a small change in the patch which updates the type inference
rule for void/null. Prior to the change the expressions were being inferred as
`Double` in this case. With the change it is appropriately inferred as `String`
(since rest of the expressions within this UDF (`GREATEST('a', 'b', null )`) is
interpreted as string.
