Description

SPARK-18368 fixes regexp_replace when it is serialized. One of the reviews requested updating the tests so that all expressions that are tested using checkEvaluation are first serialized. That caused several new [test failures], so this issue is to add serialization to the tests (pick commit 10805059) and fix the bugs serialization exposes.
