Pulled out a BinaryExpression interface. It's used in the planbuilder phase to determine the type of any bindvars in binary expressions. This makes bindvar type inference for statements like
select * from t1 where :v1 + 1 = :v2
work as expected, and works for any binary expression involving a column and a bindvar.
