* invoke check_expression() for all vcol_info's in
mysql_prepare_create_table() to check for FK CASCADE
* also check for SET NULL and SET DEFAULT
* to check against existing FKs when a vcol is added in ALTER TABLE,
old FKs must be added to the new_key_list just like other indexes are
* check columns recursively, if vcol1 references vcol2,
flags of vcol2 must be taken into account
* remove check_table_name_processor(), put that logic under
check_vcol_func_processor() to avoid walking the tree twice
Problem:
During ALTER, when filling stored column info, wrong column number is used.
This is because we ignored virtual column when iterating over columns in
table and lead to debug assertion.
Fix:
In InnoDB table cache object, vcols are on stored on one list, stored and
normal columns are stored in another list.
When looking for stored column, ignore the virtual columns to get the right
column number of stored column.
