* exp_util.ads, exp_util.adb:
This patch replaces a number of occurrences of explicit tests for N_Null
with calls to Known_Null. This improves tracking of null values, since
Known_Null also catches null constants, and variables currently known to
be null, so we get better tracking.
(Ensure_Defined): create an itype reference only in the scope of the
itype.
(Side_Effect_Free): A selected component of an access type that
denotes a component with a rep clause must be treated as not
side-effect free, because if it is part of a linked structure its
value may be affected by a renaming.
(Expand_Subtype_From_Expr): For limited objects initialized with build
in place function calls, do nothing; otherwise we prematurely introduce
an N_Reference node in the expression initializing the object, which
breaks the circuitry that detects and adds the additional arguments to
the called function. Bug found working in the new patch for statically
allocated dispatch tables.
(Is_Library_Level_Tagged_Type): New subprogram.
(Remove_Side_Effects): If the expression of an elementary type is an
operator treat as a function call.
(Make_Literal_Range): If the index type of the array is not integer, use
attributes properly to compute the constraint on the resulting aggregate
which is a string.

* freeze.ads, freeze.adb (Freeze_Entity): If the entity is a
class-wide type whose base type is an incomplete private type, leave
class-wide type unfrozen so that freeze nodes can be generated
properly at a later point.

(Expand_Interface_Thunk): Fix bug in the expansion assuming that the
first formal of the thunk is always associated with the controlling
type. In addition perform the following code cleanup: remove formal
Thunk_Alias which is no longer required, cleanup evaluation of the

object declaration, for diagnostic purposes.

construction of statically allocated dispatch tables.

Additional modifications to handle non-static generation of dispatch
tables. Take care of building tables for asynchronous interface types
(Make_Tags): New subprogram that generates the entities associated with
the primary and secondary tags of Typ and fills the contents of Access_
Disp_Table. In case of library-level tagged types imports the forward
declaration of the primary tag that will be declared later by Make_DT.
(Expand_Interface_Conversion): In case of access types to interfaces
replace an itype declaration by an explicit type declaration to avoid

tests optimized out.

* exp_ch4.adb (Expand_N_In): Add warnings for range tests optimized out.
(Get_Allocator_Final_List): For the case of an anonymous access type
that has a specified Associated_Final_Chain, do not go up to the
enclosing scope.
(Expand_N_Type_Conversion): Test for the case of renamings of access
parameters when deciding whether to apply a run-time accessibility
check.
(Convert_Aggr_In_Allocator): Use Insert_Actions to place expanded
aggregate code before allocator, and ahead of declaration for
temporary, to prevent access before elaboration when the allocator is
an actual for an access parameter.
(Expand_N_Type_Conversion): On an access type conversion involving an
access parameter, do not apply an accessibility check when the
operand's original node was an attribute other than 'Access. We now
create access conversions for the expansion of 'Unchecked_Access and
'Unrestricted_Access in certain cases and clearly accessibility should
not be checked for those.

* exp_ch6.ads, exp_ch6.adb (Add_Call_By_Copy_Code): For an actual that
includes a type conversion of a packed component that has been expanded,
recover the original expression for the object, and use this expression
in the post-call assignment statement, so that the assignment is made
to the object and not to a back-end temporary.
(Freeze_Subprogram): In case of primitives of tagged types not defined
at the library level force generation of code to register the primitive
in the dispatch table. In addition some code reorganization has been
done to leave the implementation clear.
(Expand_Call): When expanding an inherited implicit conversion,
preserve the type of the inherited function after the intrinsic
operation has been expanded.

* exp_ch2.ads, exp_ch2.adb
(Expand_Entry_Parameter.In_Assignment_Context): An implicit dereference
of an entry formal appearing in an assignment statement does not assign
to the formal.
(Expand_Current_Value): Instead of calling a routine to determine
whether the prefix of an attribute reference should be optimized or
not, prevent the optimization of such prefixes all together.

* lib-xref.adb (Generate_Reference.Is_On_LHS): An indexed or selected
component whose prefix is known to be of an access type is an implicit
dereference and does not assign to the prefix.

value of a conversion that requires a range check, set the type of the
temporary before rewriting the node, so that the type is always
