Bug #9775	Stored procedures: crash if create function that returns enum or set

Description:
During CREATE FUNCTION ... RETURNS ENUM ... or CREATE FUNCTION RETURNS SET ...,
crash.

This may turn out to be a duplicate of BUG#9102 ("RETURNS BLOB"), BUG#9495 ("RETURNS MEDIUMTEXT"), BUG#9537 ("RETURNS LONGTEXT"), or even already-closed BUG#3788 ("RETURNS BINARY"). I begin to suspect a pattern.

How to repeat:
mysql> create function fenum () returns enum('a','b') return 'a'//
ERROR 2013 (HY000): Lost connection to MySQL server during query

clause.
