Server crashes if one tries to prepare simple query which contains constant expression
involving IN and CONVERT_TZ(), which should read time zone description from system

This bug only present in 5.0, it does not occur in 4.1.

How to repeat:
Restart server to ensure that any time zone mentioned in CONVERT_TZ() function
will require access to system tables.

Run the following query:
prepare stmt1 from "select '2004-01-01 00:00:00' IN (CONVERT_TZ('2004-01-01 00:00:00', 'Europe/Moscow', 'UTC'))";

Server will crash.
