Bug#17203: "sql_no_cache sql_cache" in views created from prepared statement

Browse Source 
The problem was that we restored SQL_CACHE, SQL_NO_CACHE flags in SELECT
statement from internal structures based on value set later at runtime, not
the original value set by the user.

The solution is to remember that original value.
