* 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.
