	* sem_ch12.adb (Instantiate_Formal_Subprogram): In the subprogram
	renaming declaration, use the Slocs of the formal parameters from the
	declaration of the formal subprogram when creating the formal parameter
	entities in the renaming declaration.
	(Analyze_Formal_Type_Declaration): Change the placement of the error
	message concerning illegal known discriminants. It is now posted on the
	type rather than on the first discriminant. This change ensures early
	error report.
	(Freeze_Subprogram_Body): If the generic subprogram is nested within
	the package body that contains the instance, do not generate an
	out-of-place freeze node for the enclosing package.
	(Collect_Previous_Instantiations): Ignore internal instantiations
	generated for formal packages.
	(Validate_Derived_Type_Instance): Add a check that when a formal
	derived type is Known_To_Have_Preelab_Init then the actual type must
	have preelaborable initialization, and issue an error when this
	condition is violated.
