Review Comment:
> Why make this change? If it were a dialect conversion, it could be
determined using `SqlOperator`.
Can we modify the function to
SqlBasicFunction.create(SqlKind.RLIKE, ReturnTypes.BOOLEAN_NULLABLE,
OperandTypes.STRING_STRING);
Using SQL Kind.RLIKE, it seems that there is a need for a kind in HiveSQL
Dialect to perform conversion judgments, and I am not sure if I understand it
correctly
