------------------------------------------
The proposed improvement can affect end-2-end performance? If so, could you show us a query here?

> Two constructors in SpecificInternalRow can be made faster by using while loops instead of maps. This was originally noticed while working on SPARK-32532 and SPARK-32533 and will have impacts on performance of reading ORC and Avro files. Profiled the change using added benchmarks in SPARK-32531 for nested and array'd structs.
