Add tests for UNBOUNDED syntax ambiguity
There is a syntactic ambiguity in the SQL standard. Since UNBOUNDED
is a non-reserved word, it could be the name of a function parameter
and be used as an expression. There is a grammar hack to resolve such
cases as the keyword. Add some tests to record this behavior.
