crash in main.views (and other view + PS tests)
When a view is merged, mark its select_lex as already optimized, otherwise
its where clause (which doesn't have to be a valid Item after merging)
might be accessed later. But don't do that for inserts (where a view cannot
be simply merged, if one later needs to insert into it).
