* sem_ch3.adb (Check_Entry_Contracts): New procedure, subsidiary
of Analyze_Declarations, that performs pre-analysis of
pre/postconditions on entry declarations before full analysis
is performed after entries have been converted into procedures.
Done solely to capture semantic errors.

call to Denote_Same_Function.

* exp_ch7.adb (Find_Last_Init): Remove obsolete code. The
logic is now performed by Process_Object_Declaration.
(Process_Declarations): Recognize a controlled deferred
constant which is in fact initialized by means of a
build-in-place function call as needing finalization actions.
(Process_Object_Declaration): Insert the counter after the
build-in-place initialization call for a controlled object. This
was previously done in Find_Last_Init.
* exp_util.adb (Requires_Cleanup_Actions): Recognize a controlled
deferred constant which is in fact initialized by means of a
build-in-place function call as needing finalization actions.

* sem_ch3.adb (Analyze_Object_Declaration): Add a missing check
for optimized aggregate arrays with qualified expressions.
* exp_aggr.adb (Expand_Array_Aggregate): Fix block and
conditional statement in charge of deciding whether to perform
in-place expansion. Specifically, use Parent_Node to jump over
the qualified expression to the object declaration node. Also,
a check has been inserted to skip the optimization if SPARK 2005
is being used in strict adherence to RM 4.3(5).
