Description

The bug fixes a few issues related to nested expressions:
1) The nested expressions were not being validated at all.
2) UDFRegExp was not handled correctly, but issue was not caught because of the previous issue.
3) HIVE-5642 will not show up when this jira is fixed, but still added a sanity check to validate the number of arguments.
