3806 global symbol, creat one if none exists and emit
3807 error if there is a clash.

3810 the function can be called from resolve.c.

3813 already defined or if references were to another type.

3819 component reference to a derived type array into a temporary array

3822 derived type after the call.

3824 that is followed by a component reference.
3825 (gfc_conv_function_call): Detect an aliased actual argument with
