	* einfo.ads (Corresponding_Record_Component): New alias
	for Node21 used for E_Component and E_Discriminant.
	* einfo.adb (Corresponding_Record_Component): New function.
	(Set_Corresponding_Record_Component): New procedure.
	(Write_Field21_Name): Handle Corresponding_Record_Component.
	* sem_ch3.adb (Inherit_Component): Set
	Corresponding_Record_Component for every component in
	the untagged case.  Clear it afterwards for non-girder
	discriminants.
	* gcc-interface/decl.c (gnat_to_gnu_entity)
	<E_Record_Type>: For a derived untagged type with discriminants
	and constraints, apply the constraints to the layout of the
	parent type to deduce the layout.
	(field_is_aliased): Delete.
	(components_to_record): Test DECL_ALIASED_P directly.
	(annotate_rep): Check that fields are present except for
	an extension.
	(create_field_decl_from): Add DEBUG_INFO_P
	parameter and pass it in recursive and other calls.  Add guard
	for the manual CSE on the size.
	(is_stored_discriminant): New predicate.
	(copy_and_substitute_in_layout): Consider only
	stored discriminants and check that original fields are present
	in the old type.  Deal with derived types.  Adjust call to
	create_variant_part_from.

	* exp_ch6.adb (Expand_Call_Helper): When locating the
	accessibility entity created for an access parameter, handle
	properly a reference to a formal of an enclosing subprogram. if
	the reference appears in an inherited class-wide condition, it
	is the rewriting of the reference in the ancestor expression,
	but the accessibility entity must be that of the current formal.

	* exp_ch4.adb (Expand_Non_Binary_Modular_Op): New subprogram.
	(Expand_N_Op_Add, Expand_N_Op_Divide, Expand_N_Op_Minus,
	Expand_N_Op_Multiply, Expand_N_Op_Or, Expand_N_Op_Subtract):
	Call Expand_Non_Binary_Modular_Op.
