unknown 170ae2d252 Bug #31562: HAVING and lower case ...

The columns in HAVING can reference the GROUP BY and 
SELECT columns. There can be "table" prefixes when
referencing these columns. And these "table" prefixes
in HAVING use the table alias if available.
This means that table aliases are subject to the same
storage rules as table names and are dependent on 
lower_case_table_names in the same way as the table 
names are.
Fixed by :
1. Treating table aliases as table names
and make them lowercase when printing out the SQL
statement for view persistence.
2. Using case insensitive comparison for table 
aliases when requested by lower_case_table_names
