[C++][Gandiva] Expression cache should not use ToString on data type

    XMLWordPrintableJSON

      Description

      The expression cache in gandiva generates uses the ToString() method of arrow::DataType() for both hashing and equality.

      This is error-prone - we should have a visitor for generating hash, and use the equality visitor for comparison.
