(Replace_Anonymous_Access_To_Protected_Subprogram): Handle properly an
anonymous access to protected subprogram that is the return type of the
specification of a subprogram body.
* sem_ch6.adb:
(Analyze_Subprogram_Body): if the return type is an anonymous access to
subprogram, freeze it now to prevent access anomalies in the back-end.
* exp_ch9.adb: Minor code cleanup.
Make sure that new declarations are inserted into the tree before
analysis (from code reading).

* sem_ch3.adb (Access_Subprogram_Declaration): Adding missing support
for N_Formal_Object_Declaration nodes. Adding kludge required by
First_Formal to provide its functionality with access to functions.
(Replace_Anonymous_Access_To_Protected_Subprogram): Add missing support
for anonymous access types returned by functions.
* sem_ch5.adb (Analyze_Assignment): Code cleanup to avoid duplicate
conversion of null-excluding access types (required only once to force
the generation of the required runtime check).
* sem_type.adb (Covers): minor reformating
* checks.adb (Null_Exclusion_Static_Checks): Avoid reporting errors
with internally generated nodes. Avoid generating the error inside init
procs.
* sem_res.adb (Resolve_Membership_Test): Minor reformating.
(Resolve_Null): Generate the null-excluding check in case of assignment
to a null-excluding object.
(Valid_Conversion): Add missing support for anonymous access to
subprograms.
* sem_ch6.adb (Check_Return_Subtype_Indication): Add missing support for
anonymous access types whose designated type is an itype. This case
occurs with anonymous access to protected subprograms types.
(Analyze_Return_Type): Add missing support for anonymous access to
protected subprogram.
* sem_eval.adb (Subtypes_Statically_Match): In case of access to
subprograms addition of missing check on matching convention. Required
to properly handle access to protected subprogram types.
* exp_ch3 (Build_Assignment): Code cleanup removing duplicated check on
null excluding access types.

* exp_aggr.adb (Build_Record_Aggr_Code): Perform a conversion of the
target to the type of the aggregate in the case where the target object
is class-wide.
* exp_ch5.adb (Expand_Simple_Function_Return): When the function's
result type is class-wide and inherently limited, and the expression
has a specific type, create a return object of the specific type, for
more efficient handling of returns of build-in-place aggregates (avoids
conversions of the class-wide return object to the specific type on
component assignments).
* sem_ch6.adb (Check_Return_Subtype_Indication): Suppress the error
about a type mismatch for a class-wide function with a return object
having a specific type when the object declaration doesn't come from
source. Such an object can result from the expansion of a simple return.

check when the type
of the extended return is an anonymous access_to_subprogram type.
