* 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.

(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

Thunk_Alias which is no longer required, cleanup evaluation of the

* sem_ch6.ads, sem_ch6.adb (Analyze_Subprogram_Body): Force the
generation of a freezing node to ensure proper management of null
excluding access types in the backend.
(Create_Extra_Formals): Test base type of the formal when checking for
the need to add an extra accessibility-level formal. Pass the entity E
on all calls to Add_Extra_Formal (rather than Scope (Formal) as was
originally being done in a couple of cases), to ensure that the
Extra_Formals list gets set on the entity E when the first entity is
added.
(Conforming_Types): Add missing calls to Base_Type to the code that
handles anonymous access types. This is required to handle the
general case because Process_Formals builds internal subtype entities
to handle null-excluding access types.
(Make_Controlling_Function_Wrappers): Create wrappers for constructor
functions that need it, even when not marked Requires_Overriding.
Improve warnings for in out parameters
(Analyze_Function_Return): Warn for disallowed null return
Warn on return from procedure with unset out parameter
Ensure consistent use of # in error messages
(Check_Overriding_Indicator): Add in parameter Is_Primitive.
(Analyze_Function_Return): Move call to Apply_Constraint_Check before
the implicit conversion of the expression done for anonymous access
types. This is required to generate the code of the null excluding
check (if required).

* sem_warn.ads, sem_warn.adb (Check_References.Publicly_Referenceable):
A formal parameter is never publicly referenceable outside of its body.
(Check_References): For an unreferenced formal parameter in an accept
statement, use the same warning circuitry as for subprogram formal
parameters.
(Warn_On_Unreferenced_Entity): New subprogram, taken from
Output_Unreferenced_Messages, containing the part of that routine that
is now reused for entry formals as described above.
(Goto_Spec_Entity): New function
(Check_References): Do not give IN OUT warning for dispatching operation
Improve warnings for in out parameters
(Test_Ref): Check that the entity is not undefinite before calling
Scope_Within, in order to avoid infinite loops.
Warn on return from procedure with unset out parameter
Improved warnings for unused variables
