Description

The change IMPALA-11645: Remove PrintThriftEnum functions in debug-util.cc introduced the function PrintValue() which we use to convert Thrift types to strings. This function now uses operator<<, which is provided for the generated thrift types. However, Thrift also generates a to_string() function that is overloaded for Thrift types. It would be more efficient to use this instead of involving streams with operator<<.
