[SPARK-8770][SQL] Create BinaryOperator abstract class.
Our current BinaryExpression abstract class is not for generic binary
expressions, i.e. it requires left/right children to have the same type.
However, due to its name, contributors build new binary expressions that don't
have that assumption (e.g. Sha) and still extend BinaryExpression.
This patch creates a new BinaryOperator abstract class, and update the
analyzer o only apply type casting rule there. This patch also adds the notion
of "prettyName" to expressions, which defines the user-facing name for the
expression.
