	* einfo.adb (Write_Field28_Name): Update the choices for
	Extra_Formals.
	* einfo.ads: Update the use of Extra_Formals in various entities.
	* exp_ch6.adb (Add_Task_Actuals_To_Build_In_Place_Call): Code
	reformatting. Handle the case where the function call returns
	an incomplete type coming from a limited with context. Generate
	a reference to the _master when the master id is associated
	with an access type.
	(Is_Build_In_Place_Function_Call): Code
	reformatting. The Alfa mode case must appear first since otherwise
	we will carry out the function name retrieval regardless of the
	compilation mode.
	(Make_Build_In_Place_Call_In_Allocator): Code
	reformatting. Handle the case where the function call returns
	an incomplete type coming from a limited with context. Remove
	the reference creation when adding the task-related actuals,
	this is now done in Add_Task_Actuals_To_Build_In_Place_Call.
	* exp_ch7.adb (Make_Set_Finalize_Address_Call): Remove local
	variable Call. Remove the useless wrapping of Set_Finalize_Address
	when the finalization master is a build-in-place extra formal. The
	whole mechanism of controlled allocation in a build-in-place
	context is already protected by an if statement.
	* sem_aux.adb (Is_Immutably_Limited_Type): Handle the case
	where the type might be related to a function which returns an
	incomplete type coming from a limited with.
	* sem_ch6.adb (Create_Extra_Formals): Comment
	reformatting. Handle the case where the function returns an
	incomplete type coming from a limited with context.

	* lib-xref-alfa.adb (Is_Alfa_Reference): Improve test for constant
	objects and rewrite case statement as /if/elsif/endif.
