an aspect expression, when the prefix of the reference is the
current instance of the type to which the aspect applies.
* sem_ch6.adb (Enter_Overloaded_Entity): Do not warn about
hiding unless we're actually hiding something. The previous
code would (for example) warn about a "<" on a record type
because it incorrectly thought it was hiding the "<" on Boolean
in Standard. We need to check that the homonym S is in fact a
homograph of a predefined operator.

* exp_util.ads, exp_util.adb (Build_Procedure_Form): Moved here
from exp_ch6.adb, for use in SPARK_To_C mode when creating the
procedure equivalent to a function returning an array, when this
construction is deferred to the freeze point of the function.
* sem_util.adb (Is_Unchecked_Conversion_Instance): Include a
function that renames an instance of Unchecked_Conversion.
* freeze.adb (Freeze_Subprogram): Generate the proper procedure
declaration for a function returning an array.
* exp_ch6.adb (Build_Procedure_Form): Moved to exp_util.

2016-04-20 Ed Schonberg <schonberg@adacore.com>
* sem_util.ads, sem_util.adb (Is_Expanded_Priority_Attribute):
New predicate to determine that in a context with full run-time,
a function call is an expansion of a reference to attribute
Priority.
* sem_ch5.adb (Analyze_Function_Call): use it.
* exp_ch5.adb (Expand_N_Subprogram_Call): use it.
* einfo.adb Flag286 is now used as Is_Exception_Handler.
(Is_Exception_Handler): New routine.
(Set_Is_Exception_Handler): New routine.
(Write_Entity_Flags): Output the status of Is_Exception_Handler.
* einfo.ads New attribute Is_Exception_Handler along with
occurrences in entities.
(Is_Exception_Handler): New routine along with pragma Inline.
(Set_Is_Exception_Handler): New routine along with pragma Inline.
* exp_ch7.adb (Make_Transient_Block): Ignore blocks generated
for exception handlers with a choice parameter.
* sem_ch11.adb (Analyze_Exception_Handlers): Mark the scope
generated for a choice parameter as an exception handler.

* sem_ch3.adb (Build_Derived_Access_Type): Remove dead code.
(Constrain_Discriminated_Type): In an instance, if the type has
unknown discriminants, use its full view.
(Process_Subtype): Check that the base type is private before
adding subtype to Private_Dependents list.
* sem_ch4.adb (Analyze_Selected_Component): A reference to the
current instance of a task type is legal if the prefix is an
expression of that task type and the selector is an entry or
entry family.

* a-cfdlli.ads (List): Type is no longer tagged, not needed. Move
varsize field at the end for efficiency.
