does not work well together". Now using simplier and more correct implementation of st_lex::unlink_first_table()/link_first_table_back() (It also nicely handles case when global table list is created because of implictly used time zone tables). (2nd attempt) Fix for bug #7705 "CONVERT_TZ() crashes with subquery/WHERE on index column". Implemented new approach for caching objects for constant time zone arguments. Now instead of determining whenever these arguments are constants and performing time zone lookup at fix_fields() stage, we do it on first get_date() invocation. Cleanup of global @@time_zone variable handling.
